Jupyter command not found on Mac OS Catalina - jupyter-notebook

Question

I'm trying to run Jupyter notebook on Mac OS Catalina. I followed the basic instructions:
pip3 install jupyter
I tried everything that is mentioned in the other answers here on stack overflow. I have edited the .bash_profile file, and I have tried to start the notebook with
~/local/bin/jupyter
But nothing is working. My .bash_profile looks like this:
export PATH="/usr/local/mysql/bin:/usr/local/bin:/usr/local/git/bin:$PATH"
# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH
How can I run Jupyter Notebook on Mac OS Catalina?

Answer 1

I have encountered the similar annoying problem and here is my one-line solution:
Open terminal and type:
brew install jupyter
If you haven't install brew on your Mac, please follow the instruction here: https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Wait for around 10 minutes until the installation finishes and try jupyter again.
Explain:
It helps download a lot of "Catalina" related packages, like
==> Downloading https://homebrew.bintray.com/bottles/jupyterlab-2.1.5.catalina.bottle.tar.gz
......
==> Downloading https://homebrew.bintray.com/bottles/ipython-7.16.1.catalina.bottle.tar.gz
......

From the comments:
Try opening Visual Studio Code and installing Jupyter extensions there if the above method does not work.
