Pip (also known as Pip3 — corresponding to Python 3) is a tool for installing and managing Python packages (the name "Pip" is a recursive anagram for "Pip Installs Packages"). It is considered by many to be essential for developing Python packages. If you're developing or distributing Python packages, Pip is a must-have. In this guide, you will be shown a few methods for installing Pip, as well as a few steps you can take to verify the installation was successful, giving you a smooth start to Python 3 package development. Let's review how to install Pip on CentOS 7.
Python is a programming language that has a design philosophy that emphasizes code readability. It is widely considered to be a very easy programming language to master because of that focus on readability. Python is open source, and will run a multitude of platforms including, but not limited to various Linux/UNIX distributions (CentOS, Ubuntu, Fedora, Debian, etc.), Microsoft Windows, and Mac OS X. This article only discusses an install on Pip on CentOS 7.
- This article will guide the reader through steps used to install Pip on CentOS 7.
- The steps below are shown with root access on a Core Managed CentOS 7 VPS from Liquid Web.
- You will use any one of the options that follow.
Step 1: Add the EPEL Repository
The Extra Packages for Enterprise Linux (EPEL) repository is already included on many CentOS 7 servers. Since Pip is included in the standard EPEL repository, having it installed should ensure Pip is installed on CentOS 7 successfully:
sudo yum install epel-release
Answer "y" when prompted to continue.
Step 2: The Installation
Option 1: Install Pip on CentOS 7 with Yum
Before running any installations with Yum, it’s recommended that existing packages be updated:
sudo yum -y update
Now that existing packages have been updated, you can install python-pip and any required dependencies:
yum -y install python-pip
If you see something like the following, that means Pip was previously installed:
Setting up Install Process Package python-pip-7.1.0-1.el6.noarch already installed and latest version Nothing to do
Otherwise, you’ll see something like the following:
yum -y install python-pip Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.us.oneandone.net * extras: mirror.trouble-free.net * updates: centos.mirrors.tds.net Resolving Dependencies --> Running transaction check ---> Package python2-pip.noarch 0:8.1.2-8.el7 will be installed --> Processing Dependency: python-setuptools for package: python2-pip-8.1.2-8.el7.noarch --> Running transaction check ---> Package python-setuptools.noarch 0:0.9.8-7.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =================================================================== Package Arch Version Repository Size =================================================================== Installing: python2-pip noarch 8.1.2-8.el7 base 1.5 M Installing for dependencies: python-setuptools noarch 0.9.8-7.el7 base 396 k Transaction Summary =================================================================== Install 1 Package (+1 Dependent package) Total download size: 1.9 M Installed size: 7.7 M Downloading packages: (1/2): python-setuptools-0.9.8-7.el7.noarch.rpm | 396 kB 00:00 (2/2): python2-pip-8.1.2-8.el7.noarch.rpm | 1.5 MB 00:00 --------------------------------------------------------------- Total 2.9 MB/s | 1.9 MB 00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : python-setuptools-0.9.8-7.el7.noarch 1/2 Installing : python2-pip-8.1.2-8.el7.noarch 2/2 Verifying : python2-pip-8.1.2-8.el7.noarch 1/2 Verifying : python-setuptools-0.9.8-7.el7.noarch 2/2 Installed: python2-pip.noarch 0:8.1.2-8.el7 Dependency Installed: python-setuptools.noarch 0:0.9.8-7.el7 Complete!
Option 2: Install Pip on CentOS 7 with Curl and Python
You can also use cURL to download and use Python to install Pip on CentOS 7:
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
Once you’ve downloaded the install script, you can run it with the following command:
Your output will vary, but it should look something like the output shown below:
python get-pip.py Collecting pip Downloading https://files.pythonhosted.org/packages/fe/ef/60d7ba03b5c442309ef42e 7d69959f73aacccd0d86008362a681c4698e83/pip-21.1.3-py3-none-any.whl (1.5MB) 100% |████████████████████████████████| 1.5MB 1.2MB/s Collecting wheel Downloading https://files.pythonhosted.org/packages/65/63/39d04c74222770ed1589c0e aba06c05891801219272420b40311cd60c880/wheel-0.36.2-py2.py3-none-any.whl Installing collected packages: pip, wheel Found existing installation: pip 9.0.1 Uninstalling pip-9.0.1: Successfully uninstalled pip-9.0.1 Successfully installed pip-21.1.3 wheel-0.36.2
Option 3: Download and Install Pip on CentOS 7 for Python 2.7
The most recent version of Pip requires Python 3.7 or greater. If you are unable to upgrade your version of Python, here's how you can install Pip on CentOS 7 for older versions:
curl "https://bootstrap.pypa.io/2.7/get-pip.py" -o "get-pip.py"
Once you've downloaded the install script, you can run it with this command:
You'll get an output similar to what is seen with the above option.
Step 3: Wrap Up / Verify The Installation
To verify that you have installed Pip correctly, try installing and uninstalling a package.
The following command is to install a new package:
pip install <package_name>
You can uninstall an existing package with the following command:
pip uninstall <package_name>
And here's what that might look like:
pip install h11 Collecting h11 Downloading h11-0.14.0-py3-none-any.whl (58 kB) |████████████████████████████████| 58 kB 2.8 MB/s Installing collected packages: h11 Successfully installed h11-0.14.0 pip uninstall h11 Found existing installation: h11 0.14.0 Uninstalling h11-0.14.0: Would remove: /opt/lib/python3.9/site-packages/h11-0.14.0.dist-info/* /opt/lib/python3.9/site-packages/h11/* Proceed (Y/n)? y Successfully uninstalled h11-0.14.0
Other Useful Commands
Here are some other commands that might be useful.
Show help and general options:
Check what version of Pip is installed:
The output will be something like this:
pip 21.2.4 from /opt/lib/python3.9/site-packages/pip (python 3.9)
Or the output may look like this:
pip 20.3.4 from /usr/lib/python2.7/site-packages (python 2.7)
List all of the Python packages that are installed on your system:
Your list won't be the same, but the output will look like this:
pip list Package Version ---------------------------------- -------------------- aiohttp 3.8.4 aiosignal 1.3.1 alabaster 0.7.12 [...many more packages...] yarl 1.8.2 zict 2.0.0 zipp 3.6.0
Show information about the specified Python package:
pip show <package_name>
Here is an example of the output:
pip show pylint Name: pylint Version: 2.9.6 Summary: python code static checker Home-page: https://github.com/PyCQA/pylint Author: Python Code Quality Authority Author-email: firstname.lastname@example.org License: GPL-2.0-or-later Location: /opt/lib/python3.9/site-packages Requires: astroid, toml, mccabe, isort Required-by: spyder
In this guide, you’ve been shown how to install Pip on CentOS 7. Managing and installing Python packages is essential for any Python developer or package distributor. You were shown three options for installing the Pip tool — with the third for older installations — and a verification step to check that the installation was successful.

CentOS 7 Approaching End of Life (EOL) Date
CentOS 7 goes EOL in June 2024. It is expected that there will no longer be security updates available after that date. Active support of CentOS 7 stopped in August 2020.
In most cases, AlmaLinux 8 is the OS being used where CentOS 7 is being replaced. The organization responsible will support the AlmaLinux OS 8 until at least until 2029. Our knowledge base contains a helpful article covering how to install the Pip Package Manager on AlmaLinux.
