Question

After installing with pip install jupyter, terminal still cannot find jupyter notebook.

Ubuntu simply says command not found. Similar with ipython. Did pip not get install properly or something? How does Ubuntu know where to look for executables installed with pip?

Answer 1

I tried both,

pip install jupyter

and

pip3 install jupyter

but finally got it done using

sudo -H pip install jupyter

Answer 2

I'm on Mojave with Python 2.7 and after pip install --user jupyter the binary went here:

/Users/me/Library/Python//2.7/bin/jupyter
