How to install pip (Python) on pfSense

Once you have installed python on your pfSense, you might notice that it is missing pip:

[2.6.0-RELEASE][root@pfsense02.techoverflow.net]/root: pip
pip: Command not found.

and also python3.8 -m pip doesn’t work:

[2.6.0-RELEASE][root@pfsense02.techoverflow.net]/root: python3.8 -m pip
/usr/local/bin/python3.8: No module named pip

Installing it is rather easy, however:

python3.8 -m ensurepip

After that, you can run pip using

python3 -m pip
