Installing PIP on Ubuntu 18.04

 6 min

This article includes steps to install PIP on Ubuntu 18.04.

Prerequisite :

Commands mentioned in this article are for Ubuntu 18.04 LTS server. We have logged in as a root user.

First of all, we need t to verify that the Python is installed :

Run the following command, to verify that Python is installed on your server :

root@host:~# python

Python 3.6.8 (default, Jan 14 2019, 11:02:34)

[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux

Type "help", "copyright", "credits" or "license" for more information.


This command checks the Python version and also verifies if Python 3 is installed on your Ubuntu system.

Type Ctrl+C to exit the Python shell.

# Install PIP

Start updating Ubuntu

root@host:~# apt update
root@host:~# python3 --version

Python 3.7.5

Then, install PIP.

root@host:~# apt install python3-pip




After this operation, 129 MB of additional disk space will be used.

Setting up python3.6-dev (3.6.8-1~18.04.3) ...

Setting up libpython3-dev:amd64 (3.6.7-1~18.04) ...

Setting up build-essential (12.4ubuntu1) ...

Setting up python3-dev (3.6.7-1~18.04) ...

Processing triggers for man-db (2.8.3-2ubuntu0.1) ...

Processing triggers for libc-bin (2.27-3ubuntu1) ...


Now, check the version of your installed PIP, using the following command.

root@host:~# pip3 --version

pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

#Using cases

We have several options to use PIP.

Either we can stay within a virtual environment and test our programs within a distinct or virtual Python environment. Or, we can also run PIP globally, this can make a program to run on the server itself.

In this example, we are going to work on our projects within the virtual Python environment (by using venv) so that it will limit the interaction with other projects for their dependencies. Additionally, it will also avoid a huge conflict that can take place with the system’s default Python environment. We run the following code, to display all the available options for PIP :

root@host:~# pip3 --help
