What is "pip command not found" error ?

The python-pip package manager works as an independent package manager on Linux distribution. This means you need to install the pip tool separately from python programs.

The pip command is not found an error raised on your Linux terminal window if the pip is not installed independently on Ubuntu 20.04 system. Therefore, before installing any package using pip, the pip tool should be installed on your Ubuntu system.

When are working with the python3 version, you can use the pip or pip3 as well while installing a new python package on your system.
For example, you want to install a python package ‘scrapy’ using the pip command:

$ pip3 install scrapy

There can be two versions of pip (at the time of writing article python4 was not released so once python4 is available, it is possible we have another version of pip) i.e. from python2 and python3.

So based on your requirement and environment you can choose to install the respective pip version (although python2 is mostly deprecated and you can choose to install pip from Python3).

$ curl https://bootstrap.pypa.io/pip/2.7/get-pip.py --output get-pip.py
