python - Pyinstaller：AttributeError：模块“枚举”没有属性“IntFlag”

问题描述

我需要将python代码编译为exe。我找到了一些指导如何做到这一点，我被要求为此安装 PyInstaller：

pip install --upgrade pyinstaller

但我得到下一个错误：

C:\Users\alonat>pip install pyinstaller
Collecting pyinstaller

你知道如何解决这个错误吗？

解决方案

如果已安装，请卸载 enum34 模块，然后重试。

pip uninstall enum34

这将解决错误，如果您需要 enum34 将其降级为 enum34==1.1.8

此处有用的信息 为什么 Python 3.6.1 会抛出 AttributeError：模块 'enum' 没有属性 'IntFlag'？ https://github.com/iterative/dvc/issues/1995
