如何识别python版本与pip版本

查询python版本

 python -V

输出

Python 2.7.5

查询pip在哪里

whereis pip3

输出

pip3: /usr/bin/pip3 /usr/bin/pip3.6

查询pip对应的python

cat /usr/bin/pip3

输出

#!/usr/bin/python3

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

try:
    from pip import main
except ImportError:
    # user has most probably upgraded pip in their home
    # so let them run it anyway until ~/.local/bin makes it in front of the PATH
    from pip._internal import main

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

关注一下第一行,指明了python路径

#!/usr/bin/python3
