Checking your pip version

The first thing you’ll probably want to do is check which pip version you have in the first place. You can then compare that to the latest published version to see whether you should upgrade. The command for this is thankfully very simple:

pip --version

How to upgrade pip the latest version

Upgrading pip is again very easy process. Just run the following:

python -m pip install --upgrade pip

How to upgrade pip to specfic version

Just run the following:

python -m pip install  pip==your.version.number

How to downgrade pip

If you do find that you need to rollback your pip version due to bugs, incompatibilities, or any other reason, find the version number you want to roll back to and then run this command:

python -m pip install pip==your.version.number
