Issues with PIP installation when Python2 and 3 coexist

With Python2 and Python3 Multiple versions installed, we use PIP to install modules that are prone to problems:

[[email protected] ~]# python-m pip install Psutil

>>> Import Psutil

Traceback (most recent):

Importerror:cannot import name ' _psutil_linux '

This error, not without the Psutil module reported the wrong, but because my system contains python2 and Python3, so when using PIP installation, will be installed in 2, resulting in this error

When we installed 2 and 3, when using PIP to install the module, we need to declare before the PIP is 2 or 3

[[email protected] ~]# python-m pip install psutil# my system has python2.7 and Python3.6,python is version 3.6.

I used python in front of Pip to declare that I am currently using 3 instead of python2.7, so the installation is normal.

PS: Personal opinion, if there is a wrong place, please correct me.
