解决方案

这是因为您的 enum 不是标准库 enum 模块。您可能已经安装了包 enum34。

检查是否是这种情况的一种方法是检查属性枚举。文件

import enum
print(enum.__file__)  
# standard library location should be something like 
# /usr/local/lib/python3.6/enum.py

从 python 3.6 开始， enum34 库不再与标准库兼容。该库也不是必需的，因此您只需将其卸载即可。

pip uninstall -y enum34 如果您需要代码在 <=3.4 和 >3.4 的 python 版本上运行，您可以尝试将 enum-compat 作为要求。它只为没有标准库枚举的旧版本的 python 安装 enum34。
