Jupyter notebook command does not work on Mac

Question

I installed jupyter using pip on my macbook air. Upon trying to execute the command jupyter notebook, I get an error

jupyter: 'notebook' is not a Jupyter command 

I used the --h option to get a listing of all jupyter commands and indeed, 'notebook' is not one of the commands. I am running python 2.7 and it was already installed before I installed jupyter.

I searched on google and I see a similar problem some people have faced with the latest version of jupyter but I don't see any solutions. Can somebody point me in the right direction?

which -a pip: /usr/local/bin/pip

which -a jupyter: /usr/local/bin/jupyter

Answer 1

I had the same problem. After looking to a gazillion of pages on line and trying as many solutions, this is the only thing that worked for me:

pip uninstall notebook pip install --upgrade notebook 

I am not sure that the "upgrade" is necessary, but after that I had

jupyter-notebook 

and

jupyter notebook 

as commands.

Answer 2

I got the same error as you when which jupyter is /usr/local/bin/jupyter. I managed to solve the case by updating/upgrading all my ipython packages

sudo -H pip install --upgrade "ipython[all]" 

I managed to solve the case in OS X El-Capitan 10.11.5 and Ubuntu Linux 16.04. My Jupyter version after the upgrade is 4.1.0. My Python is 2.7.11+. My Pip version is 8.1.2.
