Find the command that will summon your Python 3.10 or Python 3.11 installation
(can be python, python3, python3.10, python3.11 or py depending on the system you are currently using).
Now, stick to it! You don't want to scatter files everywhere on your computer or to do a multi-version install.
Don't let any error happen un-noticed! If you see an error, then there must be an error! Consider it seriously! Most people assume that seing errors is normal as long as nothing crashes. It may not be that bad but a missing package means a broken Sardine!
As funny as it may sound, I am not the owner of the sardine package on Pypi. Sardine is named sardine-system. Some people sometimes end up installing a totally unrelated tool!
