pyinstall ：打包 .exe 文件报错AttributeError: module ‘enum‘ has no attribute ‘IntFlag‘

有疑问的地方	参考博文
一、环境搭建	Python GUI图形化小工具编程学习-- PySide2 环境搭建（一）
二、实例演示	Python GUI图形化小工具编程学习-- Demo 实例演示（二）
三、打包失败	pyinstall ：打包 .exe 文件报错AttributeError: module ‘enum‘ has no attribute ‘IntFlag‘
四、pyinstaller打包有问题	pyinstaller打包 .py 文件为可执行的 .exe程序
五、打包后的.exe文件打开报错	PySide2：打开.exe文件报错：Failed to execute script

研究将 .py 文件通过 pyinstaller 打包成可执行的 .exe 文件时

pyinstaller -F --icon=pyexe.ico demo.py

出现了如下的报错信息：

解决问题：

一、 这可能是由包Enum34引起的。因为Python3.4有一个标准库枚举模块，所以您应该卸载Enum34，因为在Python3.6中添加了Enum.Intflag，所以它不再与标准库中的枚举兼容，卸载 enum34

pip3 uninstall enum34

二、卸载完成后再次执行打包命令：pyinstaller -F --icon=pyexe.ico demo.py
