title: How can I use Jupyter Notebook on macOS Catalina (without anaconda)?
body: <p>I've tried since yesterday to launch anaconda after I install the new version of macOS Catalina (before I understand that it is a beta version), and I finally find a way. But unfortunately, I can not launch Jupiter notebook from terminal because apparently it is not installed and it doesn't want to neither. How can I fix that ? </p>
