The PIP management tool for Python

Python has two well-known package management tools easy_install.py and PIP. In Python2.7 's installation package, easy_install.py is installed by default, and Pip requires us to install it manually.

Workaround:

Install Python-devel, which is the Python header file and the static library package

[email protected] ~]# Yum install Python-devel

6. Install the Psutil module again
