Python pyinstaller类库使用学习总结

实践环境

python3 .9.13

pyinstaller-6.10.0-py3-none-manylinux2014_x86_64.whl

CentOS 7.9

win11

实践操作

生成Linux版可执行文件

安装Python

# yum install -y gcc zlib* openssl-devel libffi-devel
# wget https://www.python.org/ftp/python/3.6.13/Python-3.6.13.tgz
# mkdir -p /usr/local/python
# mv Python-3.9.13.tgz /usr/local/python
# tar -xvzf Python-3.9.13.tgz
# cd python-3.9.13
# ./configure --prefix=/usr/local/python/python3.9.13 --enable-shared
# make && make install

说明：

1、如果不安装libffi-devel，运行pyinstaller时会报错：ModuleNotFoundError: No module named '_ctypes'，以下

# pyinstaller simulator.py
Traceback (most recent call last):
  File "/usr/bin/pyinstaller", line 8, in <module>
    sys.exit(_console_script_run())
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/__main__.py", line 231, in _console_script_run
    run()
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/__main__.py", line 172, in run
    parser = generate_parser()
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/__main__.py", line 137, in generate_parser
    import PyInstaller.building.build_main
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/building/build_main.py", line 28, in <module>
    from PyInstaller.building.api import COLLECT, EXE, MERGE, PYZ
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/building/api.py", line 33, in <module>
    from PyInstaller.building.splash import Splash  # argument type validation in EXE
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/building/splash.py", line 23, in <module>
    from PyInstaller.depend import bindepend
  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/depend/bindepend.py", line 15, in <module>
    import ctypes.util
  File "/usr/local/python/python3.9.13/lib/python3.9/ctypes/__init__.py", line 8, in <module>
    from _ctypes import Union, Structure, Array
ModuleNotFoundError: No module named '_ctypes'

2、如果编译Python时不携带--enable-shared选项，运行pyinstaller时会报类似如下错误：

  File "/usr/local/python/python3.9.13/lib/python3.9/site-packages/PyInstaller/building/build_main.py", line 671, in assemble
    raise PythonLibraryNotFoundError()
PyInstaller.exceptions.PythonLibraryNotFoundError: Python library not found: libpython3.9.so.1.0, libpython3.9.so
    This means your Python installation does not come with proper shared library files.
    This usually happens due to missing development package, or unsuitable build parameters of the Python installation.

    * On Debian/Ubuntu, you need to install Python development packages:
      * apt-get install python3-dev
      * apt-get install python-dev
    * If you are building Python by yourself, rebuild with `--enable-shared` (or, `--enable-framework` on macOS).

添加/usr/lib64/libpython3.9.so.1.0文件

# find / -name libpython3.9.so.1.0
/root/Python-3.9.13/libpython3.9.so.1.0
/usr/local/python/python3.9.13/lib/libpython3.9.so.1.0
# cp /usr/local/python/python3.9.13/lib/libpython3.9.so.1.0 /usr/lib64/libpython3.9.so.1.0

说明：如果不执行该操作，运行pyinstaller时生成可执行文件时可能报类似如下错误：

# pyinstaller simulator.py
/usr/local/python/python3.9.13/bin/python3.9: error while loading shared libraries: libpython3.9.so.1.0: cannot open shared object file: No such file or directory

安装 pyinstaller

# pip3 install pyinstaller -i http://mirrors.aliyun.com/pypi/simple --trusted-host mirrors.aliyun.com

创建软连接，避免直接执行 pyinstaller 命令时，提示 pyinstaller: command not found

# find / -name pyinstaller
/usr/local/python/python3.9.13/bin/pyinstaller
# 
# ln -fs /usr/local/python/python3.9.13/bin/pyinstaller /usr/binpyinstaller
# pyinstaller -v
6.10.0

注意，生成的文件是不带配置的，程序所需配置需要自己添加

生成Windows版可执行文件

安装 pyinstaller

同Linux，安装完成后，会在${PYTHON_HOME}\Scripts目录下生成pyinstaller.exe，为方便执行，将其所在路径添加到环境变量

生成可执行文件

同Linux

pyinstaller [选项] program_entry_file.py

pyinstaller常用选项

-y 档输出目录下的存在旧生成文件时，不提示删除确认提示，直接删除
-F,--onefile 打包为一个独立文件
--add-data <source>;<dest_dir> (适用Win) 、--add-data <source>:<dest_dir> (适用Linux) 用于将非python文件如配置，打包进程序。
- <source>是资源文件的路径，可以是相对路径或绝对路径，建议使用绝对路径。
- <dest_dir>是资源文件在打包后在可执行文件中的目标目录路径。是相对于应用程序顶层目录的目标目录，如果要将文件放入应用程序顶层目录，则使用 . 作为 <dest_dir>。注意：如果该目录路径不存在，则会自动创建
--add-data 可重复使用，以支持单次添加多个文件的需求

例子：

假设我们有一个Python项目，其中包含一个名为config.ini的配置文件。希望在使用PyInstaller打包项目时，将这个配置文件也一起打包进去。

cd /d D:\PyProjects\ZenTaoTestcaseHelper
pyinstaller --add-data "D:\PyProjects\ZenTaoTestcaseHelper\config.json;." testcase_helper.py

生成目标结果文件路径如下：

D:\PyProjects\ZenTaoTestcaseHelper\dist\testcase_helper\testcase_helper.exe
D:\PyProjects\ZenTaoTestcaseHelper\dist\testcase_helper\config.json

运行可执行文件无法正确读取配置文件解决方案

实践时遇到过这样的情况：

直接使用python program_entry_file.py的方式运行程序时，可正确执行不报错，直接运行打包生成的可执行文件时，出现报错，提示相关配置文件不存在。

经过分析发现，直接运行可执行文件时，读取配置文件的路径不对，为了避免这种情况，可在代码中添加判断，设置采用可执行文件的方式运行时的配置文件读取路径:

program_entry_file.py(程序入口文件)中判断是否是运行打包生成的可执行文件，如果是，则设置环境变量，获取可执行文件所在目录

sys_executable = sys.executable
if not sys_executable.endswith('python.exe') and not re.findall('python\d*$', sys_executable):
    os.environ['EXECUTABLE_DIR'] = os.path.dirname(sys.executable)

其它需要读取配置文件的py文件中添加判断

假设我们期望可执行文件从位于同级目录的conf目录下的program.conf文件中读取配置

config_file_path = 'conf/program.conf'
if os.getenv('EXECUTABLE_DIR'):
    config_file_path = os.path.join(os.environ['EXECUTABLE_DIR'], config_file_path)
