我刚刚为 MacOSX 安装了 Python 3.6.1
当我尝试运行控制台(或者使用 Python 3运行任何东西)时,会抛出这个错误:
AttributeError: module 'enum' has no attribute 'IntFlag'
$ /Library/Frameworks/Python.framework/Versions/3.6/bin/python3

class RegexFlag(enum.IntFlag):
AttributeError: module 'enum' has no attribute 'IntFlag'
类 IntFlag 存在于枚举.py 中。那么,为什么要抛出 AttributeError 呢?
