Linux 下使用pyinstaller 打包 PyQt 应用 缺少 libpython问题

如果打包时出现错误：

OSError: Python library not found: Python8, libpython3.8m.dylib, Python, libpython3.8.dylib, .Python
    This would mean your Python installation doesn't come with proper library files.
    This usually happens by missing development package, or unsuitable build parameters of Python installation.

    * On Debian/Ubuntu, you would need to install Python development packages
      * apt-get install python3-dev
      * apt-get install python-dev
    * If you're building Python by yourself, please rebuild your Python with `--enable-shared` (or, `--enable-framework` on Darwin)
 

出现上述错误后，需要重新启安装 python，将 libpython3.8m.dylib 复制到 /usr/lib 目录：

cp -R libpython3.8m.dylib /usr/lib

源码安装Python：

1、下载 python包：Python-3.8.1.tgz

2、解压pyt
