摘记 pyinstaller 使用自定义 spec
下面的是官网的文档,
我们可以用自定义spec的方式把想要的文件打包到目标文件夹里面
例如:
我们在程序中用了一个图标 test.ico,
如果我们只用 pyinstaller -w test.py
那生成的 dist/test/ 文件夹中是没有test.ico的,需要手动拷贝过去
如果我们首先生成spec : pyi-makespec -w test.py, 就会先生成 test.spec(当前目录下),
类似
# -*- mode: python -*-
block_cipher = None
a = Analysis(['test.py'],
pathex=['D:\\Test\\python'],
binaries=None,
datas=None,
hiddenimports=[],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
exe = EXE(pyz,
a.scripts,
exclude_binaries=True,
name='SearchPhoneUI',
debug=False,
strip=False,
upx=True,
console=False , icon='test.ico')
coll = COLLECT(exe,
a.binaries,
a.zipfiles,
a.datas,
strip=False,
upx=True,
name='test')
那我们就可以修改这个spec文件,a.datas +=[('phonebook.ico','D:\\Test\\python\\test.ico','DATA')]
# -*- mode: python -*-
block_cipher = None
a = Analysis(['test.py'],
pathex=['D:\\Test\\python\\'],
binaries=None,
datas=None,
hiddenimports=[],
hookspath=[],
runtime_hooks=[],
excludes=[],
win_no_prefer_redirects=False,
win_private_assemblies=False,
cipher=block_cipher)
a.datas +=[(test.ico','D:\\Test\\python\\test.ico','DATA')]
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
exe = EXE(pyz,
a.scripts,
exclude_binaries=True,
name='SearchPhoneUI',
debug=False,
strip=False,
upx=True,
console=False , icon='test.ico')
coll = COLLECT(exe,
a.binaries,
a.zipfiles,
a.datas,
strip=False,
upx=True,
name='test')
加红的就是新加的内容,指定了需要打包的文件,
最后执行 pyinstaller -w test.spec 就可以了
Using Spec Files
When you execute
pyinstaller
options..myscript.py
the first thing PyInstaller does is to build a spec (specification) file myscript.spec
. That file is stored in the --specpath=
directory, by default the current directory.
The spec file tells PyInstaller how to process your script. It encodes the script names and most of the options you give to the pyinstaller
command. The spec file is actually executable Python code.PyInstaller builds the app by executing the contents of the spec file.
For many uses of PyInstaller you do not need to examine or modify the spec file. It is usually enough to give all the needed information (such as hidden imports) as options to the pyinstaller
command and let it run.
There are four cases where it is useful to modify the spec file:
- When you want to bundle data files with the app.
- When you want to include run-time libraries (
.dll
or.so
files) that PyInstaller does not know about from any other source. - When you want to add Python run-time options to the executable.
- When you want to create a multiprogram bundle with merged common modules.
These uses are covered in topics below.
You create a spec file using this command:
pyi-makespec
options name.py
[other scripts ...]
The options are the same options documented above for the pyinstaller
command. This command creates the name.spec
file but does not go on to build the executable.
After you have created a spec file and modified it as necessary, you build the application by passing the spec file to the pyinstaller
command:
pyinstaller
options name.spec
When you create a spec file, most command options are encoded in the spec file. When you build from a spec file, those options cannot be changed. If they are given on the command line they are ignored and replaced by the options in the spec file.
Only the following command-line options have an effect when building from a spec file:
- –upx-dir=
- –distpath=
- –workpath=
- –noconfirm
- –ascii
Spec File Operation
After PyInstaller creates a spec file, or opens a spec file when one is given instead of a script, the pyinstaller
command executes the spec file as code. Your bundled application is created by the execution of the spec file. The following is an shortened example of a spec file for a minimal, one-folder app:
block_cipher = None
a = Analysis(['minimal.py'],
pathex=['/Developer/PItests/minimal'],
binaries=None,
datas=None,
hiddenimports=[],
hookspath=None,
runtime_hooks=None,
excludes=None,
cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
cipher=block_cipher)
exe = EXE(pyz,... )
coll = COLLECT(...)
The statements in a spec file create instances of four classes, Analysis
, PYZ
, EXE
and COLLECT
.
- A new instance of class
Analysis
takes a list of script names as input. It analyzes all imports and other dependencies. The resulting object (assigned toa
) contains lists of dependencies in class members named:scripts
: the python scripts named on the command line;pure
: pure python modules needed by the scripts;binaries
: non-python modules needed by the scripts;datas
: non-binary files included in the app.
- An instance of class
PYZ
is a.pyz
archive (described under Inspecting Archives below), which contains all the Python modules froma.pure
. - An instance of
EXE
is built from the analyzed scripts and thePYZ
archive. This object creates the executable file. - An instance of
COLLECT
creates the output folder from all the other parts.
In one-file mode, there is no call to COLLECT
, and the EXE
instance receives all of the scripts, modules and binaries.
You modify the spec file to pass additional values to Analysis
and to EXE
.
Adding Files to the Bundle
To add files to the bundle, you create a list that describes the files and supply it to the Analysis
call. To find the data files at run-time, see Run-time Information.
Adding Data Files
To have data files included in the bundle, provide a list that describes the files as the value of the datas=
argument to Analysis
. The list of data files is a list of tuples. Each tuple has two values, both of which must be strings:
- The first string specifies the file or files as they are in this system now.
- The second specifies the name of the folder to contain the files at run-time.
For example, to add a single README file to the top level of a one-folder app, you could modify the spec file as follows:
a = Analysis(...
datas=[ ('src/README.txt', '.') ],
...
)
You have made the datas=
argument a one-item list. The item is a tuple in which the first string says the existing file is src/README.txt
. That file will be looked up (relative to the location of the spec file) and copied into the top level of the bundled app.
The strings may use either /
or \
as the path separator character. You can specify input files using “glob” abbreviations. For example to include all the .mp3
files from a certain folder:
a = Analysis(...
datas= [ ('/mygame/sfx/*.mp3', 'sfx' ) ],
...
)
All the .mp3
files in the folder /mygame/sfx
will be copied into a folder named sfx
in the bundled app.
The spec file is more readable if you create the list of added files in a separate statement:
added_files = [
( '/mygame/sfx/*.mp3', 'sfx' ),
( 'src/README.txt', '.' )
]
a = Analysis(...
datas = added_files,
...
)
You can also include the entire contents of a folder:
added_files = [
( '/mygame/data', 'data' ),
( '/mygame/sfx/*.mp3', 'sfx' ),
( 'src/README.txt', '.' )
]
The folder /mygame/data
will be reproduced under the name data
in the bundle.
Using Data Files from a Module
If the data files you are adding are contained within a Python module, you can retrieve them using pkgutils.get_data()
.
For example, suppose that part of your application is a module named helpmod
. In the same folder as your script and its spec file you have this folder arrangement:
helpmod
__init__.py
helpmod.py
help_data.txt
Because your script includes the statement import helpmod
, PyInstaller will create this folder arrangement in your bundled app. However, it will only include the .py
files. The data file help_data.txt
will not be automatically included. To cause it to be included also, you would add a datas
tuple to the spec file:
a = Analysis(...
datas= [ ('helpmod/help_data.txt', 'helpmod' ) ],
...
)
When your script executes, you could find help_data.txt
by using its base folder path, as described in the previous section. However, this data file is part of a module, so you can also retrieve its contents using the standard library function pkgutil.get_data()
:
import pkgutil
help_bin = pkgutil.get_data( 'helpmod', 'help_data.txt' )
In Python 3, this returns the contents of the help_data.txt
file as a binary string. If it is actually characters, you must decode it:
help_utf = help_bin.decode('UTF-8', 'ignore')
Adding Binary Files
To add binary files, make a list of tuples that describe the files needed. Assign the list of tuples to the binaries=
argument of Analysis.
Normally PyInstaller learns about .so
and .dll
libraries by analyzing the imported modules. Sometimes it is not clear that a module is imported; in that case you use a --hidden-import=
command option. But even that might not find all dependencies.
Suppose you have a module special_ops.so
that is written in C and uses the Python C-API. Your program imports special_ops
, and PyInstaller finds and includes special_ops.so
. But perhaps special_ops.so
links to libiodbc.2.dylib
. PyInstaller does not find this dependency. You could add it to the bundle this way:
a = Analysis(...
binaries=[ ( '/usr/lib/libiodbc.2.dylib', 'libiodbc.dylib' ) ],
...
As with data files, if you have multiple binary files to add, create the list in a separate statement and pass the list by name.
Advanced Methods of Adding Files
PyInstaller supports a more advanced (and complex) way of adding files to the bundle that may be useful for special cases. See The TOC and Tree Classes below.
Giving Run-time Python Options
You can pass command-line options to the Python interpreter. The interpreter takes a number of command-line options but only the following are supported for a bundled app:
v
to write a message to stdout each time a module is initialized.u
for unbuffered stdio.W
and an option to change warning behavior:W ignore
orW once
orW error
.
To pass one or more of these options, create a list of tuples, one for each option, and pass the list as an additional argument to the EXE call. Each tuple has three elements:
- The option as a string, for example
v
orW ignore
. - None
- The string
OPTION
For example modify the spec file this way:
options = [ ('v', None, 'OPTION'), ('W ignore', None, 'OPTION') ]
a = Analysis( ...
)
...
exe = EXE(pyz,
a.scripts,
options, <--- added line
exclude_binaries=...
)
Spec File Options for a Mac OS X Bundle
When you build a windowed Mac OS X app (that is, running in Mac OS X, you specify the --onefile --windowed
options), the spec file contains an additional statement to create the Mac OS X application bundle, or app folder:
app = BUNDLE(exe,
name='myscript.app',
icon=None,
bundle_identifier=None)
The icon=
argument to BUNDLE
will have the path to an icon file that you specify using the --icon=
option. The bundle_identifier
will have the value you specify with the --osx-bundle-identifier=
option.
An Info.plist
file is an important part of a Mac OS X app bundle. (See the Apple bundle overview for a discussion of the contents of Info.plist
.)
PyInstaller creates a minimal Info.plist
. You can add or overwrite entries in the plist by passing aninfo_plist=
parameter to the BUNDLE call. The value of this argument is a Python dict. Each key and value in the dict becomes a key and value in the Info.plist
file. For example, when you use PyQt5, you can set NSHighResolutionCapable
to True
to let your app also work in retina screen:
app = BUNDLE(exe,
name='myscript.app',
icon=None,
bundle_identifier=None
info_plist={
'NSHighResolutionCapable': 'True'
},
)
The info_plist=
parameter only handles simple key:value pairs. It cannot handle nested XML arrays. For example, if you want to modify Info.plist
to tell Mac OS X what filetypes your app supports, you must add a CFBundleDocumentTypes
entry to Info.plist
(see Apple document types). The value of that keyword is a list of dicts, each containing up to five key:value pairs.
To add such a value to your app’s Info.plist
you must edit the plist file separately after PyInstallerhas created the app. However, when you re-run PyInstaller, your changes will be wiped out. One solution is to prepare a complete Info.plist
file and copy it into the app after creating it.
Begin by building and testing the windowed app. When it works, copy the Info.plist
prepared by PyInstaller. This includes the CFBundleExecutable
value as well as the icon path and bundle identifier if you supplied them. Edit the Info.plist
as necessary to add more items and save it separately.
From that point on, to rebuild the app call PyInstaller in a shell script, and follow it with a statement such as:
cp -f Info.plist dist/myscript.app/Contents/Info.plist
Multipackage Bundles
Note
This feature is broken in the PyInstaller 3.0 release. Do not attempt building multipackage bundles until the feature is fixed. If this feature is important to you, follow and comment on PyInstaller Issue #1527.
Some products are made of several different apps, each of which might depend on a common set of third-party libraries, or share code in other ways. When packaging such an product it would be a pity to treat each app in isolation, bundling it with all its dependencies, because that means storing duplicate copies of code and libraries.
You can use the multipackage feature to bundle a set of executable apps so that they share single copies of libraries. You can do this with either one-file or one-folder apps. Each dependency (a DLL, for example) is packaged only once, in one of the apps. Any other apps in the set that depend on that DLL have an “external reference” to it, telling them to extract that dependency from the executable file of the app that contains it.
This saves disk space because each dependency is stored only once. However, to follow an external reference takes extra time when an app is starting up. All but one of the apps in the set will have slightly slower launch times.
The external references between binaries include hard-coded paths to the output directory, and cannot be rearranged. If you use one-folder mode, you must install all the application folders within a single parent directory. If you use one-file mode, you must place all the related applications in the same directory when you install the application.
To build such a set of apps you must code a custom spec file that contains a call to the MERGE
function. This function takes a list of analyzed scripts, finds their common dependencies, and modifies the analyses to minimize the storage cost.
The order of the analysis objects in the argument list matters. The MERGE function packages each dependency into the first script from left to right that needs that dependency. A script that comes later in the list and needs the same file will have an external reference to the prior script in the list. You might sequence the scripts to place the most-used scripts first in the list.
A custom spec file for a multipackage bundle contains one call to the MERGE function:
MERGE(*args)
MERGE is used after the analysis phase and before EXE
and COLLECT
. Its variable-length list of arguments consists of a list of tuples, each tuple having three elements:
- The first element is an Analysis object, an instance of class Analysis, as applied to one of the apps.
- The second element is the script name of the analyzed app (without the
.py
extension). - The third element is the name for the executable (usually the same as the script).
MERGE examines the Analysis objects to learn the dependencies of each script. It modifies these objects to avoid duplication of libraries and modules. As a result the packages generated will be connected.
Example MERGE spec file
One way to construct a spec file for a multipackage bundle is to first build a spec file for each app in the package. Suppose you have a product that comprises three apps named (because we have no imagination) foo
, bar
and zap
:
pyi-makespec
options as appropriate...foo.py
pyi-makespec
options as appropriate...bar.py
pyi-makespec
options as appropriate...zap.py
Check for warnings and test each of the apps individually. Deal with any hidden imports and other problems. When all three work correctly, combine the statements from the three files foo.spec
, bar.spec
and zap.spec
as follows.
First copy the Analysis statements from each, changing them to give each Analysis object a unique name:
foo_a = Analysis(['foo.py'],
pathex=['/the/path/to/foo'],
hiddenimports=[],
hookspath=None)
bar_a = Analysis(['bar.py'], etc., etc...
zap_a = Analysis(['zap.py'], etc., etc...
Now call the MERGE method to process the three Analysis objects:
MERGE( (foo_a, 'foo', 'foo'), (bar_a, 'bar', 'bar'), (zap_a, 'zap', 'zap') )
The Analysis objects foo_a
, bar_a
, and zap_a
are modified so that the latter two refer to the first for common dependencies.
Following this you can copy the PYZ
, EXE
and COLLECT
statements from the original three spec files, substituting the unique names of the Analysis objects where the original spec files have a.
, for example:
foo_pyz = PYZ(foo_a.pure)
foo_exe = EXE(foo_pyz, foo_a.scripts, ... etc.
foo_coll = COLLECT( foo_exe, foo_a.binaries, foo_a.datas... etc.
bar_pyz = PYZ(bar_a.pure)
bar_exe = EXE(bar_pyz, bar_a.scripts, ... etc.
bar_coll = COLLECT( bar_exe, bar_a.binaries, bar_a.datas... etc.
(If you are building one-file apps, there is no COLLECT
step.) Save the combined spec file as foobarzap.spec
and then build it:
pyi-build foobarzap.spec
The output in the dist
folder will be all three apps, but the apps dist/bar/bar
and dist/zap/zap
will refer to the contents of dist/foo/
for shared dependencies.
There are several multipackage examples in the PyInstaller distribution folder under /tests/old_suite/multipackage
.
Remember that a spec file is executable Python. You can use all the Python facilities (for
and with
and the members of sys
and io
) in creating the Analysis objects and performing the PYZ
, EXE
and COLLECT
statements. You may also need to know and use The TOC and Tree Classes described below.
Globals Available to the Spec File
While a spec file is executing it has access to a limited set of global names. These names include the classes defined by PyInstaller: Analysis
, BUNDLE
, COLLECT
, EXE
, MERGE
, PYZ
, TOC
and Tree
, which are discussed in the preceding sections.
Other globals contain information about the build environment:
DISTPATH
- The relative path to the
dist
folder where the application will be stored. The default path is relative to the current directory. If the--distpath=
option is used,DISTPATH
contains that value. HOMEPATH
- The absolute path to the PyInstaller distribution, typically in the current Python site-packages folder.
SPEC
- The complete spec file argument given to the
pyinstaller
command, for examplemyscript.spec
orsource/myscript.spec
. SPECPATH
- The path prefix to the
SPEC
value as returned byos.split()
. specnm
- The name of the spec file, for example
myscript
. workpath
- The path to the
build
directory. The default is relative to the current directory. If theworkpath=
option is used,workpath
contains that value. WARNFILE
- The full path to the warnings file in the build directory, for example
build/warnmyscript.txt
.
