Had a heck of a time getting .zsh to recognize jupyter, every time I entered it I would get “command not found”. Turns out miniconda didn’t adjust $PATH correctly. If you run into this issue on macOS Catalina or later, I recommend doing the following:
~% export PATH=$PATH:/Users/[yourusername]/anaconda3/bin
That should solve your issue. I’m not sure how pervasive this problem is, but I thought I’d share as it had me hung up for a few study sessions. Happy Coding!
