Installing pip on Ubuntu 20.04

You can install pip either through a virtual environment or while installing Python. It depends on which one you prefer. I will be using a virtual environment to install pip 21 on Ubuntu 20.04.

1. Run system updates

First, we need to update our repositories to make them up to date by issuing update and upgrade commands on our terminal.

$ sudo apt update && apt upgrade -y

2. Create a virtual environment

A virtual environment is used to manage Python packages for different projects. It creates an isolated environment for pip packages.

Begin by creating a directory where your virtual environment will be located.

$ sudo mkdir nextgentips
$ cd nextgentips

Next, create a virtual environment

$ python3 -m venv nextvenv

Nextvenv is the name given to a virtual environment.

In case you encounter the following error, follow the instruction in order to make necessary changes.

The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv

Run the following command to correct the following error.

$ sudo apt install python3.8-venv

The following command will install python 3.8 venv.

Output
The following NEW packages will be installed:
  python3.8-venv
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

Press Y to allow installation to continue.

Go ahead and run this command again python3 -m venv nextvenv, this time it will run successfully.

$ python3 -m venv nextvenv

To start using the virtual environment, run the following command to activate the virtual environment.

$ source nextvenv/bin/activate

When you see something like this (nextvenv) [email protected]:~/nextgentips#, you know that you have activated the virtual environment successfully.

3. Upgrade pip to latest version

The installation will ask you to upgrade to the latest pip. To run upgrade use the following command;

$ python -m pip install --upgrade pip
Output
