Omg this is so true! I installed a package globally, but then my interpreter was using another version of python, which doesn't have the installed package. It took me an hour to find out about this. What a waste of time.
then the 'pip' is running the same version as the 'python' command (I believe, can you check and comment latter?)
(you'd still have to check your IDE if you are not running python from the CLI)
