pip3更新后install package出现ImportError: cannot import name 'main'

 

linux下pip3更新后，install包出现main不能导入的状况：

bear@bear:~/eclipse-workspace/Python-toolbox$ pip3 install pycryptodomex
Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main
ImportError: cannot import name 'main'

缘由为pip更新为10.0.0后库里面的函数有所变更形成这个问题。
解决方案：

vim  /usr/bin/pip3

# 更改前
from pip import main
if __name__ == '__main__':
sys.exit(main())


# 更改后
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())

done !
