pyinstaller 打包遇到问题：Python library not found: libpython3.9m.so.1.0, libpython3.9m.so, libpython3.9.so.1.0, libpython3.9.so, libpython3.9mu.so.1.0

背景

• 在linux部署执行python脚本的时候，要避免因为依赖带来的问题，同时不想暴露自己的代码程序，可以用pyinstaller将py文件打包成一个可执行的文件

操作

• 安装pyinstaller
  pip install pyinstaller

• 安装完成之后, 执行以下命令就会完成打包，在对应的目录下会生成一个dist目录，里面就是可执行的程序文件
  pyinstaller -F demo.py

遇到问题

`OSError: Python library not found: libpython3.9m.so.1.0, libpython3.9m.so, libpython3.9.so.1.0, libpython3.9.so, libpython3.9mu.so.1.0
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)`

在打包过程中遇到了打包不成功的问题，看报错事python缺少动态库，重点错误提示：
* If you are building Python by yourself, rebuild with --enable-shared(or,--enable-framework on macOS)
所以需要将python重新build，执行以下命令
cd /usr/local/python3.9/ ./configure --prefix=/usr/local/python3.9 --enable-shared --with-ssl make &make install
重新打包编译了python解释器，然后再执行以下, 将编译的依赖库拷贝到系统库中，
cp libpython3.so libpython3.9.so.1.0 /usr/lib64/
至此，就可以继续执行上面的打包命令了！
