更改 Jupyter Notebook (Python3) 的环境

Question

Whenever I install package using pip on my computer, they are not available in my Jupyter Notebooks. From what I figured out, they are not in the same environment. When I run

import sys
sys.executable

on the Notebook, I get

/Library/Developer/CommandLineTools/usr/bin/python3

while on the terminal I get

/Library/Frameworks/Python.framework/Versions/3.7/bin/python3

What do I do to fix this? All answers I found online assume conda in installed, but I do not use conda. Ideally I would just change the default environment the Jupyter Notebook runs in but I can't figure out how...

EDIT

I tried adding the environment as suggested in another article by using the following code in terminal:

/Library/Frameworks/Python.framework/Versions/3.7/bin/python3 -m ipykernel install --prefix=/Library/Developer/CommandLineTools/usr/bin/python3 --name 'Py3’

But it returns

Which I don't really understand.

Answer 1

You should change jupyter kernel via Kernel tab:

Use the explanation here if you want to add more kernels to jupyter: https://ipython.readthedocs.io/en/latest/install/kernel_install.html

Answer 2

Solved it by uninstalling Python 3 and then using homebrew and pyenv to install a new version in a more controlled manner and make it the system default. After a reboot it then worked.
