Cannot uninstall requirement jupyter, not installe

Question

I have installed jupyter but want to uninstall it. It however is not possible:

$ pip freeze | grep jupyter

$ pip3 freeze | grep jupyter
jupyter-client==5.1.0
jupyter-console==5.2.0
jupyter-core==4.3.0

$ pip3 uninstall jupyter 
Cannot uninstall requirement jupyter, not installed

$ which jupyter
/usr/local/bin/jupyter

What can I do to remove this jupyter?

EDIT After: sudo pip3 uninstall jupyter-client jupyter-console jupyter-core I have uninstalled this 3 packages however still remaining are (2xTab):

$ jupyter-
jupyter-bundlerextension  jupyter-nbconvert         jupyter-nbextension       jupyter-notebook          jupyter-qtconsole         jupyter-serverextension   jupyter-trust 

And pip says they are not there:

$ pip3 freeze | grep jupyter
$ pip freeze | grep jupyter

and when trying to remove any of them I got same eg:

sudo -H pip uninstall jupyter-notebook
Cannot uninstall requirement jupyter-notebook, not installed

So how to remove completelly those packages too?

Answer 1

The scripts you mention are provided by the pip package named notebook, which can be installed as part of the jupyter metapackage, but can also be installed standalone. Try

sudo -H pip uninstall notebook

Answer 2

in case you were trying to uninstall jupyter because jupyter throwing below error while running jupyter notebook
zsh: /usr/local/bin/jupyter: bad interpreter: /usr/local/opt/python/bin/python3.6: no such file or directory,

u can fix that without uninstalling jupyter using below command

Python3 : pip3 install --upgrade --force-reinstall --no-cache-dir jupyter

Python2 : pip install --upgrade --force-reinstall --no-cache-dir jupyter

Above steps worked for me in Mac
