问题
I had installed 'brew' first, then python with brew. Finally, I entered "pip install jupyter --user" to have it installed. Then I typed "Jupiter notebook" and it says "command not found". I've tried this several times already, looking up the webs to identify problems and solve but I can't seem to understand this problem. I am new to Mac as well as python and programming language. So please help me in finding and solving the problem with running Jupyter? Thank you. *p.s. below I have attached the image file of the terminal screen for your reference.
