无法直接在 Mac 上的终端中运行 Jupyter notebook

Question

I want to run jupyter notebook on my mac using jupyter notebook in the terminal, but if I run this code, it gives me an error:

vlan-2625-10-16-106-253:~ brandon$ jupyter notebook
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-notebook", line 5, in <module>
    from notebook.notebookapp import main
ModuleNotFoundError: No module named 'notebook'

But if I use /usr/local/bin/python3.7 -m jupyter notebook , then it works.

I know maybe it's because I have several versions of python on my computer, or it's because the path of jupyter is incorrect, but I don't know how to deal with it.

vlan-2625-10-16-106-253:~ brandon$ which jupyter
/usr/local/bin/jupyter
vlan-2625-10-16-106-253:~ brandon$ which python3
/usr/local/bin/python3

If I tried to uninstall jupyter by brew uninstall jupyter or pip3 uninstall jupyter and then pip3 install jupyter , it still doesn't work.

If I install jupyter again, it shows:

vlan-2625-10-16-106-253:~ brandon$ pip3 install jupyter
Defaulting to user installation because normal site-packages is not writeable

If I want to run.ipynb file in pyCharm, I also receive the same error:

I think it's the same problem as I cannot directly run jupyter notebook in the terminal. This problem has been bothering me a lot and i searched a lot but I still can't figure it out. I wonder if I can change the path of jupyter command? It would be helpful if someone can answer this.

Thanks in advance!

Answer 1

you can check if python.exe is added on path.Environment Variables >>> System variables >>> path.(This is for windows) but i think there should be sth similar.
