How to Install Pip on Ubuntu

Pip is a command-line tool that allows you to install software packages written in Python. Learn how to install Pip on Ubuntu and how to use it for installing Python applications.

To install PIP on Ubuntu 20.04, you should make sure to enable universe repository and then install python3-pip package like this:

sudo add-apt-repository universe
sudo apt install python3-pip

There are numerous ways to install software on Ubuntu. You can install applications from the software center, from downloaded deb files, from PPAs, from Snap packages, using Flatpak, using AppImage and even from the good old source code.

Here’s another way to install packages on Ubuntu. It’s called PIP and you can use it to install Python-based applications.

What is pip?

Pip stands for “Pip Installs Packages”. Pip is a command-line based package management system. It’s used to install and manage software written in the Python language.

You can use pip to install packages listed in the Python Package Index (PyPI).

As a software developer, you can use pip to install various Python modules and packages for your own Python projects.

As an end user, you may need pip for installing some applications that are developed using Python and can be installed easily using pip. One such example is the Stress Terminal application, which you can easily install with pip.

Let’s see how you can install pip on Ubuntu and other Ubuntu-based distributions.

How to install pip on Ubuntu, Linux Mint and other Ubuntu-based distributions

Ubuntu 18.04 has both Python 2 and Python 3 installed by default and hence it has two possible variants of PIP for each Python versions. Pip, by default, refers to the Python 2 version. Pip for Python 3 is referred to as pip3.

Python 2 is deprecated and not available in Ubuntu 20.04 and higher versions. You can only install PIP3.

First, make sure that Python 3 is installed on Ubuntu. To check that, use this command:

If it shows you a number like Python 3.6.6, Python 3 is installed on your Linux system.

Now you can install pip3 using the command below:

You should verify that pip3 has been installed correctly using this command:

It should show you a number like this:

This means that pip3 is successfully installed on your system.

If you really need pip2 for some reason, here’s what you need to do.

First, make sure that you have Python 2 installed. On Ubuntu, use the command below to verify.

If there’s no error and a valid output that shows the Python version, you have Python 2 installed. So now you can install pip for Python 2 using this command:

It will install pip and a number of other dependencies with it. Once installed, verify that you have pip installed correctly.

It should show you a version number, something like this:

This mans that you’ve successfully installed pip on Ubuntu.

How to use pip commands

Now that you’ve installed pip, let’s quickly see some of the basic pip commands. These commands will help you use pip commands for searching, installing and removing Python packages.

Install a package with pip

There are two ways to install a package with PIP. You either install it for the currently logged in user or you install system wide.

If you use –user option, it installs the package for the logged in user i.e. you without needing sudo access. The installed python software is available only for you and other users on your system (if any) cannot use it.

If you remove the –user option, the package will be installed system wide and it will be available for all the users on your system. You’ll need sudo access in this case.

PIP doesn’t support tab completion by default. So you need to know the exact package name that you want to install. How do you get that? I show that to you in the next section.

Search for packages using pip

To search for packages in the Python Package Index, you can use the following pip command:

For example, if you search on ‘stress’, it will show all the packages that have the string ‘stress’ in their name or description.

Remove packages installed via pip

If you want to remove a Python package installed via pip, you can use the remove option.

You can use pip instead of pip3 in the above commands if you are using pip2 in Ubuntu 18.04.

I hope this quick tip helped you install pip on Ubuntu. If you have any questions or suggestions, please let me know in the comments section below.

How to Install PIP on Ubuntu 18.04

What is PIP?

In this article, we will discuss how to install PIP on Ubuntu 18.04. PIP is a tool used to install and manage Python packages. This tutorial will show how to install and check the version of PIP as well as run a few basic commands for using PIP on Ubuntu 18.04.

The Python programming language is deemed to be one of the most popular and easiest to learn due to its emphasis on code readability. Python is cross-platform, which means it can be run on multiple operating systems, including Windows Server OS. We do need to note that PIP is not installed by default on Ubuntu 18.04.

Pre-Flight Check

Verify Python Is Installed

To verify that Python is installed on your server, run the following command:

This checks the Python version and ensures that Python 3 is installed on our Ubuntu system. Exit out of the Python shell by typing Ctrl+C.

Install PIP

Let’s start by updating Ubuntu.

Next, we install PIP.

Now, let’s check the version we have installed.

Use Cases

In order to use PIP, we have several options. We can stay within a virtual environment to test out programs within a distinct or “virtual” Python environment, or we can run PIP globally, which runs the programs on the server itself. In this case, we will work on our projects within a virtual Python environment (using venv) to limit any interaction with the project’s dependencies and to avoid wider conflicts with the system’s default Python environment. To show all of the available options for pip, we can run:

To search for a specific package, we can use:

To see all of the installed packages, we can run:

This will usually output a significant number of packages.

To install a package using PIP, we use:

Finally, to uninstall a package using PIP, we simply run:

Does python3 come with PIP?

Yes pip comes with python3 since version 3.4

Should I install pip or pip3?

Install Pip if you are using python version older than 3.0 and install pip3 if you want to manage packages relevant for Python Version 3 or later.

What is the difference between pip and pip3?

pip is a package manager to install, upgrade, and uninstall python packages relevant for python versions older than 3.0. whereas pip3 is a package manager to install, upgrade, and uninstall python packages relevant for python versions greater than 3.0

If you have used Python before, chances are that you have heard of PIP. So what is it? Pip is the defacto package manager for Python packages. It allows you to install, and manage Python packages in an easy and convenient manner. PIP comes included by default in Linux systems running Python 3.4 and later. For older systems, you will need to install it. In this tutorial, we will show you how to install Pip on Ubuntu 20.04. Without much further ado, let’s dive in.

Prerequisites

Install PIP on Ubuntu 20.04

Python ships with 2 distinct flavors: Python2 and Python3 which is the latest and comes bundled in Ubuntu 20.04. Python2 can be installed thanks to the universe repository, but Python3 is the modern standard nowadays and users are encouraged to install it or upgrade from Python2. In this guide, we will demonstrate how you can install pip for both Python3 and Python2.

Install pip for Python3

Pip3 can be installed on Ubuntu using the APT package manager. To start off, update the package lists as shown.

To install pip3 run the command:

The command installs pip3 and all the Python libraries and dependencies. Upon completion of the installation, verify that pip3 is installed by running the command:

You should get output similar to what we have.

Perfect! pip3 is now installed, Let’s now see how you can install pip for Python 2.

Install pip for Python2

The Ubuntu repositories do not include pip for Python2. The only way you can install pip is by using the get-pip.py script which is included in the universe repository.

Therefore, begin by enabling the universe repository as shown:

Next, update the Ubuntu package list and install Python2 as follows:

You can check the version of Python2 by invoking the command:

You should some output similar to what we have here.

Next, proceed to download the get-pip.py script as shown.

Finally, execute the script using Python2 to install pip as shown:

Once the installation is complete, you can verify the version of pip2 by running:

How to use pip

Now that we have pip installed. Let’s go a bit further and see how you can use it to manage Python packages.

To install a package, use the syntax:

For example, to install the pandas library package which is used for data analysis and mining, run the command:

To install packages from a requirements.txt file run:

To uninstall a package run:

Those are just a few examples of how you can use the pip package manager to manage Python packages.
