If want to install python3 modules in your server then you need to use python3 -m pip install <python_module> command to install that specific module. Since here our requirement is to install the prettytable module so you need to use python3 -m pip install prettytable command to install this module as you can see below. It is worth mentioning here that this command requires you to have python3 already installed in your Server. So if it is not installed then you can check How to Install Python3 on CentOS 7 article to know more about the installation steps.

[root@localhost ~]# python3 -m pip install prettytable
WARNING: Running pip install with root privileges is generally not a good idea. Try `__main__.py install --user` instead.

NOTE:

Please note that although for the sake of demonstration I am installing module here with root privileges but this is not the recommended way in Production or in Critical Servers. Installing module using pip utility causing the setup.py script to run on the backend. This might be disastrous if any attacker planted the malicious code there with the same name.

You can also uninstall prettytable module using python3 -m pip uninstall prettytable command once you are done with it. Similarly if you want to uninstall any other python modules using python3 then you need to use python3 -m pip uninstall <python_module_name> command.

[root@localhost ~]# python3 -m pip uninstall prettytable

Another important method that you can use to install the prettytable module is through pip3.6 tool for python3. Pip3.6 is a python installer package used for managing python programs and modules. You can use pip3.6 install prettytable command to install prettytable module on Linux servers. Like prettytable module, you can install other python modules as well by using pip3.6 install <python_module> command.

[root@localhost ~]# pip3.6 install prettytable
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3.6 install --user` instead.
