I’m using Anaconda way to install the jupyter notebook.

Firstly go to the website: https://www.continuum.io/downloads

After download and install using the Graphical installer, if you try to run:

    jupyter notebook

You will probably get an error:

> zsh: command not found: jupyter

This is because:

> zsh: command not found: conda

To solve this, use your favorite editor:

    vim ~/.zshrc

Add this line at the bottom of the file:

    export PATH=”$HOME/anaconda/bin:$PATH”

Save and restart your shell, then start the Jupyer notebook again. It should now running at: http://localhost:8888/
