Pandas and Jupyter not found after upgrading to Catalina

After installed macOS Catalina, we can switch the terminal from bash to zsh. There are many advantages from using zsh instead of bash, but One of the issues with zsh is some of the frameworks (jupyter notebook,conda) are not supported directly. Once I typed jupyter notebook in terminal to run it. It displayed “zsh: no such file or directory”.

The solver is simple but very difficult to find online. If jupyter was already installed before the update and stopped working after zsh, you should be able to fix it by: 1.open zshrc in terminal by typing: open .zshrc or $open .zschrc 2. add the following line at the end of the file: source ~/.bash_profile It will ask zsh to use all the information from bash like the path of jupyter.

Hope it can help you out!

I'm answering to my own question in case it can help others ;)
