尝试从终端打开 Jupyter Notebook 不断收到 zsh 错误：找不到命令：jupyter：Python 版本：2.7.16

Question

I updated my Mac OS from High Sierra to Catalina

I asked this question before, someone suggested me this syntax: python3 -m pip install jupyter

When I tried this syntax it worked for the 1st time. After then when I completed my work and saved my file and exited Jupyter Notebook from the terminal.

When I tried to open Jupyter Notebook from my Mac Terminal the 2nd time by just writing % jupyter notebook onto the terminal, it gave me an error: zsh: command not found: jupyter

Tried all the different approaches online, but I am not able to fix this issue.

Can anyone guide me on how I can fix this problem?

Answer 1

Try pip3 install jupyter and then you should be able to run jupyter notebook form the terminal. As far as what caused the issue its hard to say it could be a variety of issues especially with the OSX update. I'm guessing though that it stems from the initial install by python3 -m pip install jupyter . I always install using pip or pip3 as I said above which will install it globally

Answer 2

Execute pip3 show jupyter . This will show you where pip has installed Jupyter. Afterwards, you can execute jupyter notebook from that directory.

Answer 3

No need to install anything or copy paste any code. Simply run the below code in your terminal after changing the user name "sudhanshukumar" to your Mac user name

/Users/sudhanshukumar/opt/anaconda3/bin/jupyter_mac.command
