After installing with pip, “jupyter: command not found”

Question

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

Ubuntu simply says command not found

Answer 1

I tried both,

pip install jupyter

and

pip3 install jupyter

but finally got it done using

sudo -H pip install jupyter

execute a command as another user -H

The -H (HOME) option requests that the security policy set the HOME environment variable to the home directory of the target user (root by default) as specified by the password database. Depending on the policy, this may be the default behavior.
