解决pip异常:No module named 'pip'

1、异常消息如下：

Traceback (most recent call last):

 File "e:\python\lib\runpy.py", line 193, in _run_module_as_main
   return _run_code(code, main_globals, None,
 File "e:\python\lib\runpy.py", line 86, in _run_code
   exec(code, run_globals)
 File "E:\python\Scripts\pip.exe\__main__.py", line 5, in <module>
ModuleNotFoundError: No module named 'pip'

2、输入Python -m ensurepip

3、python -m pip install --upgrade pip

4、至此，pip命令修复完成，又可以正常使用了
