Anaconda创建虚拟环境，使用pip报错：ModuleNotFoundError: No module named 'pip._internal.cli.main'

报错

Traceback (most recent call last):
  File "D:\ProgramData\Anaconda3\envs\commanwork\Scripts\pip-script.py", line 6, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip._internal.cli.main'

解决

• 找到pip-scripts.py文件
• 注释from pip._internal.cli.main import main,修改为from pip._internal import main
• 注释sys.exit(main()),修改为sys.exit(main.main())

# -*- coding: utf-8 -*-
import re
import sys

#from pip._internal.cli.main import main

from pip._internal import main

if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
    sys.exit(main.main())
    #sys.exit(main())
