"'alias' is not recognized as an internal or external command, operable program or batch file."

i don't understand why but it says no module named matplotlib, i then did pip3 list and matplot lib was there i then thought "maybe im using python2" so i checked my version and sure enough it was 3.10 so genuinely don't understand the issue because when i check the terminal it says its there and just in case i tried pip3 install and it said requirments already fufilled

Hii, I'm facing the same problem with matplotlib. Even though it's installed it still shows ModuleNotFoundError. I also uninstalled it and deleted it many times but still facing the same issue. Also referred to many videos but didn't come out with a solution. I tried this method too but it's written that 'alias' is not recognized as an internal or external command. Please help me out. I will be grateful.

[@ghosttogether]

Run:
pip list
pip2 list
pip3 list
under which do you see matplotlib?
that's the environment where it's installed ... you're trying to run it with py or python/python3 command from another environment
or you used relative path when importing matplotlib (switch to absolute)

@@ghosttogether Thankyou for replying :) Can you please tell exactly that how can I fix it?

@@Megha-Chakraborty How many different Pythons do you have installed? And did you add path to correct python in PATH environment variables?
