Jupyter 笔记本无法从 cmd 打开

Question

I have python 3.6 installed, and I want to install jupyter notebook (not with anaconda, just jupyter notebook). I run pip install notebook , but when I write jupyter notebook in cmd it gives an error. I had done this previously with python 3.9 and it was working, but now I don't understand the problem. Here is the error:

I had the exact same problem while trying to run jupyter notebook with python3.6 . When I changed it to 3.7 worked just fine. Maybe there is an issue with python3.6 and jupyter's compatibility.
