How To Install pip3 / pip2 In Linux

by

In this tutorial, we will learn how to install pip3 / pip2 on Rocky/ RHEL/Ubuntu/Debian/CentOS Linux Operating System. After installation method, you will get some pip command examples. It will help you to kickstart on pip command.

In this post we have covered both pip3 and pip2 installation method.

We have been maintaining this post since pip 2.x version. Please find the right Operating System where you want to install pip by using Index as given below.

Introduction: pip (Python Package Installer)

PIP is the alternate python package installer. pip is famous for easily managing the python based packages. As well as, with the help of pip you can also install the package of particular version. Most importantly pip has a feature to manage full lists of packages and corresponding version numbers, possible through a “requirements” file.

Very important to note that when we want to install particular python based package for example python 3 based package then for installing these package we need specific pip version. In such case, the pip version starts with same number which python has.

In other words, Python 3.x based package need pip3.x, Python 2.x based package need pip 2.x . We hope upto this you are clear.

It performs the same basic job as easy_install tool do but with some extra features. It can work with version control repositories (currently only Git, Mercurial, and Bazaar repositories), logs output extensively, and prevents partial installs by downloading all requirements before starting installation.

It has some disadvantages when compared to easy_install. It does not use egg files, although it does preserve egg metadata. Some setuptools features are not yet supported, and some custom setup.py features won´t work.

How To Determine Which pip Version Should We Install ?

It is very simple rule to follow, When you have Python version 3.x installed then you should use the pip 3.x version.

Similarly, if you have Python 2.x version then use pip 2.x version.

Basically pip is package manager for python so as per the Python version you must have same version of pip.

Steps To Install pip on CentOS / RHEL / Rocky Linux

In this section we will learn how to install the pip. I would like to recommend here to read the post completely because through this you know about some history of pip installation method.

Install pip In RHEL 9.x And Rocky Linux 9.x

In RHEL 9.x and Rocky Linux 9.x , the Python 3.x is shipped by default in the Operating System. Hence, the pip3 can be installed directly. There is no change in the command.

sudo dnf install -y python3-pip

Note: In CentOS Stream 9, you can install the pip with the same command but CentOS Stream is not meant for Production Server hence we are not encouraging the CentOS in our post.

Install pip In RHEL 8.x And CentOS 8.x

In CentOS 8 and RHEL 8, it is user choice to install the python version. As we know the Python 2.x has end of life in 2020.
Basically we need pip for managing the python packages. In CentOS 8/RHEL when you install the Python 3.x by dnf command , it also install pip 3 as a dependency.
So this command is for installing Python 3.x and pip3 as well.

sudo dnf install -y python3
install pip 3 on CentOS 8

If you do not have pip 3.x in your CentOS 8 / RHEL 8 system then only use the given below command.

sudo dnf install -y python3-pip


After installing pip 3 on CentOS 8 / RHEL 8, use pip3 command to manage the python packages. To check the help for pip3 command, use the given below command.

pip3 --help

Install pip in RHEL 7.x and CentOS 7.x (x86_64)

For installing pip in RHEL 7.x and CentOS 7.x . We have to take two action

  1. Install EPEL Repo as per the supporting Operating System Architecture.
  2. Install pip With Yum Command

Install EPEL Repo In RHEL 7.x and CentOS 7.x (x86_64)

First install the EPEL repo as per your Operating system version and architecture.
For detail study, you can read our previous post on EPEL.

We have already written post on “Install EPEL repo on CentOS 7 / RHEL 7” with more details. Below given command will install EPEL repo on CentOS 7 / RHEL 7.

yum install epel-release

Install pip with yum command in RHEL 7.x And CentOS 7.x

After installing the EPEL repo . Now install the pip . This will fetch the pip package from the EPEL yum repository.

yum install -y python-pip

Install pip In RHEL 6.x And CentOS 6.x

By using arch command first check if your Operating System has x86_64(64 bit) or i386(32 bit) arch. Then accordingly we will install the EPEL package.

Install EPEL Repo Supporting x86_64 Package in RHEL 6.x And CentOS 6.x

rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Install EPEL Repo Supporting i386 Package RHEL 6.x And CentOS 6.x

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

Install pip With Yum Command In RHEL 6.x And CentOS 6.x

Now install pip with yum command

yum install -y python-pip

The pip rpm will be installed. You can confirm it by using following command.
See below given reference :

[root@localhost ~]# which pip
/usr/bin/pip
[root@localhost ~]# 
[root@localhost ~]# rpm -qa|grep pip
python-pip-1.3.1-4.el6.noarch
[root@localhost ~]#

Steps To Install pip on Debian / Ubuntu

In this section, we will learn how to install pip in Debian and Ubuntu. This method is applicable to all the Debian based Operating System.

Install pip in Ubuntu 22.04 LTS

When you install the Ubuntu 22.04 LTS, you will get the python 3 version by default . So we will go straight for installing the pip on Ubuntu 22.04 LTS Operating System.

You will notice that because we have python 3 version in Ubuntu 22.04 LTS, the pip package name is also python3-pip.

sudo apt-get -y update
sudo apt install python3-pip

After installing the pip3 you can directly start using the command. To know more about the pip available options, use the command 

pip --help

Install pip in Ubuntu 20.04 LTS

As we know, the python 2.x is on sunset. In Ubuntu 20.04 LTS, it is shipped with Python 3.6. Hence, we will install the pip3 version.

Install the pip 3 by using apt-get command

sudo apt-get -y update
sudo apt install python3-pip

To manage the python 3.x packages, use the pip3 command.
You check its help.

pip3 --help

Install pip on Ubuntu 16.04 LTS and 18.04 LTS

In Ubuntu 16.04 LTS and 18.04 LTS install the pip by using apt command. In both the operating system, method is same.

sudo apt update
sudo apt install python-pip

How To Confirm pip Package Installation In Debian / Ubuntu

To confirm the package installation.Given below is the reference from my system

sharad@ubuntu:~$ sudo dpkg -l|grep pip
[sudo] password for sharad: 
ii  libpipeline1:amd64                  1.3.0-1                             amd64        pipeline manipulation library

The pip Help Section

Use –help switch along with pip command, to get more options. Read the below options, it is quite easy to use.

In this section we will see the available options in pip2.x and pip3.x . If you are working on Python or Pip you must be aware of the change in version could impact your script/work.

We are keeping this section in our record so that fellow programmers could get the benefit of this.

Why we need pip ?

Through pip we can easily manage the package/modules in Python. You can also consider it as alternate of easy_install .

Conclusion

In this article, we have learned how to install pip command in Red Hat / Rocky Linux/ Debian/ Ubuntu/ CentOS.

We have also learned to manage the packages with pip command like install,uninstall,list the modules or python packages.

At the end, we have read about the Help section in pip2.x and pip3.x version. Both version has differences in some arguments. This is because of major changes happened in Python 3.x

    • Hello Ryan,

      You can try with versioned python command. Let me know the output, it helps to troubleshoot.

      This one is to know absolute path

      `which python3.5`

      For installing package by pip

      which python3.5 -m pip install

      Regards
