Check version pip

pip3 --version

The output as below

[devopsroles@server1 ~]$ pip3 --version
pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

To install and build Python modules with pip, you need to install the Development tools:

sudo yum install python3-devel
sudo yum groupinstall 'development tools'

Installing pip2 for Python 2

sudo dnf install python2
pip2 --version
sudo yum install python2-devel
sudo yum groupinstall 'development tools'

Example, I have installed two python3 and python2 on Centos 8 as below

[devopsroles@server1 ~]$ sudo yum list installed | grep pip
libpipeline.x86_64                          1.5.0-2.el8                           @anaconda
