2.23.3. TroubleShooting - Nothing happens when i type pip
on terminal¶
Double check that you have your environment path setup correctly. It should be pointing to your “Scripts” folder, see :doc:
10min_python_starters_kit
If simply
pip
doesnt work on your terminal, then typing out the command through python is a good backup.python -m pip
