在Ubuntu上用pip install裝ansible時報錯

[email protected]:~# pip install --no-cache-dir ansible -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main
 

　　解決方案，開啟 /usr/bin/pip,修改為以下

#!/usr/bin/python
# GENERATED BY DEBIAN

import sys

# Run the main entry point, similarly to how setuptools does it, but because
# we didn't install the actual entry point from setup.py, don't use the
# pkg_resources API.
from pip import __main__
if __name__ == '
 
__main__':
    sys.exit(__main__._main())
