PIP is a recursive acronym that stands for “PIP Installs Python” (Confusing, right ?). PIP is basically a package manager to manage python-based applications & packages. PIP is used to install, remove or upgrade many of the python packages available in a repository known as Python Package Index or PyPI, in short.

Think PIP as YUM or APT for Python packages. In this tutorial, we will learn to install PIP on CentOS machines. Let’s discuss pre-requisites first.


Pre-requisites

To install the latest version of Python 3 on your system, please refer to the detailed article HERE.


Install PIP3 on CentOS

Once we have required python 3 version installed (we installed python 3.7 installed on our system using the above-mentioned tutorial), we can then proceed to install the respective PIP version on our system, which will be ‘python37-pip’ for us.

To install PIP3, we need to first install the EPEL repository on our system first (detailed tutorial HERE) & then install PIP3 using yum from the EPEL repository. Commands to install EPEL repository are mentioned below,

RHEL/CentOS 8

# dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

RHEL/CentOS 7

# rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm

RHEL/CentOS 6 (64 Bit)

# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

RHEL/CentOS 6 (32 Bit)

# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

Now that we have EPEL repo installed on our system, we can execute the following command to install PIP3 on CentOS,

# yum install python37-pip

That’s it, Python PIP3 is installed on our system. Let’s discuss some of the PIP3 commands that we can use to manage the python packages.


PIP commands

To install a package using PIP, use the following command,

# pip3 install package_name

To install a number of packages, we can create a file & mention all the packages we need to have to install ed on our system. Then run the following command to install all the packages,

# pip3 install -r packages.txt


To remove a package, run

# pip3 uninstall package_name


Command to only download a package & not install it is,

# pip3 download package_name


To list installed packages,

# pip3 list


For a complete list of options that can be used with PIP command, run

# pip3 –help
