Why?

Most websites online use pip freeze and pipe it to upgrade all modules, but freeze doesn't include these modules (output of pip list --outdated):

Package    Version Latest Type
---------- ------- ------ -----
pip        21.3.1  22.0.4 wheel
setuptools 58.1.0  62.0.0 wheel
wheel      0.37.0  0.37.1 wheel

And possibly others.

Simple solution

Pipe the result of each line in pip list --outdated.

pip list --outdated | Select-Object -Skip 2 | ForEach-Object {$_.split(' ')[0]} | ForEach-Object {pip install --upgrade $_}

Same result with short-hand version:

pip list --outdated | select -Skip 2 | % {pip install --upgrade $_.split(' ')[0]}

Workflow explained

1. Get the list of outdated pip modules. (Same list produced above)

   pip list --outdated

2. List produces a header and line separator. We want to skip those 2 lines. So:

   Select-Object -Skip 2

3. Parse the text in each line so that we extract only the names. Using space as a delimiter, we will get the first word in the first element of each array.

   ForEach-Object {$_.split(' ')[0]}

4. Pipe the output of the previous step to the command to upgrade said module.

   ForEach-Object {pip install --upgrade $_}
