摘要：

本机装有python2.7和python3.6，执行pip和pip2时没有问题，执行pip3时提示：

C:Users&;pip3
Traceback (most recent call last):
  File "e:python36librunpy.py",line 193,in _run_module_as_main
    "__main__",mod_spec)
  File "e:python36librunpy.py",line 85,in _run_code
    exec(code,run_globals)
  File "E:Python36Scriptspip3.exe__main__.py",line 2,in <module>
  File "e:python36libre.py",line 142,in <module>
    class RegexFlag(enum.IntFlag):
AttributeError: module ‘enum‘ has no attribute ‘IntFlag‘

原因:

英文：This is likely caused by the package enum34. Since python 3.4 there‘s a standard library enum module,so you should uninstall enum34,which is no longer compatible with the enum in the standard library since enum.IntFlag was added in python 3.6.

中文：这可能是由enum34包引起的。因为python 3.4中有一个标准库枚举模块，所以您应该卸载enum34，它不再与标准库中的枚举兼容，因为枚举。IntFlag是在python 3.6中添加的。

解决办法：

pip uninstall enum34 ?

#卸载enum34

卸载后执行pip3,成功，昨天整了大半天终于解决了
