I have the jupyter executable here: /usr/local/bin/jupyter

I know historically I've been using Python 2 from the Ubuntu distribution (no Anaconda) so I think that jupyter came from a system pip2 install, but I can not find a way to prove this, is there any?

Assuming the previous scenario, I've done both this: sudo /usr/local/bin/pip2 uninstall jupyter and this sudo /usr/local/bin/pip2 uninstall notebook (even if in /usr/local/bin, I still need sudo cause it seems all the files in there belong to root, for some reason), but I keep seeing that executable in here: /usr/local/bin/jupyter

Also: I know that jupyter is the affected one because now the command: jupyter notebook gives this output Error executing Jupyter command 'notebook': [Errno 2] No such file or directory.

How do I uninstall it? Why pip2 is not removing that executable file?

Edit:

I currently see this on my filesystem:

ls -lah /usr/local/bin | grep jupyter

When unistalling jupyter I've seen this:

sudo pip2 uninstall jupyter

I have uninstalled the jupyter using the following lines of code so try it.

$ sudo -H python3 -m pip uninstall jupyter_core jupyter_qtconsole nbformat nbconvert notebook

I've tried to reproduce your scenario, and I don't have jupyter installed. So at first:

sudo pip2 install jupyter

It downloaded jupyter as well as quite a few other packages, but ended first with some stray error, then, on re-run, repeatedly with:

x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c _scandir.c -o build/temp.linux-x86_64-2.7/_scandir.o

    _scandir.c:14:20: fatal error: Python.h: No such file or directory

    compilation terminated.

    error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Nevertheless, seems like at least jupyter executable has been already installed:

$ jupyter

usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]

               [--paths] [--json]

               [subcommand]

jupyter: error: one of the arguments --version subcommand --config-dir --data-dir --runtime-dir --paths is required



$ whereis jupyter

jupyter: /usr/local/bin/jupyter

But when I've tried to uninstall it:

sudo -H pip2 uninstall jupyter

Skipping jupyter as it is not installed.

In case you got the same when uninstalling, the problem might be that jupyter haven't been installed correctly at the first place.

However, I was finally able to install it correctly by installing Python dev headers: sudo apt install python-dev. And yes, sudo pip2 uninstall jupyter executed successfully, yet I still could run /usr/local/bin/jupyter after that.

Uninstalling jupyter-console package (found via pip-autoremove -L) didn't do the trick too, even though by name one may think it should.

But then I've tried to do it in an old "Norton Commander" way, to check what's inside /usr/local/bin/jupyter. Luckily, it's just a plain simple Python code, and I've noticed an interesting package reference there at line 7:

from jupyter_core.command import main

And then it was done!

$ jupyter

usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir]

               [--paths] [--json]

               [subcommand]

jupyter: error: one of the arguments --version subcommand --config-dir --data-dir --runtime-dir --paths is required

So the entire trouble is about pip not removing on uninstall the dependencies it has auto-downloaded during install..

UPDATE: Regarding the messages you've encountered while uninstalling jupiter / notebook - I didn't get any of these, but they seem not to be related to the problem discussed:

The directory '/home//.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I also get this if I run sudo pip <anything>, not sudo -H pip <anything>. Seems to be harmless.

You are using pip version 9.0.1, however version 10.0.1 is available.  

You should consider upgrading via the 'pip install --upgrade pip' command.

I already have pip 10.0.1 - that's why I don't see this.

Except these warnings, both packages are getting uninstalled correctly, as I can see.

Regarding the need for sudo, I'm not surprised as normally pip install * installs the package system-wide, and it's unlikely you will be able to write to /usr/local/lib/python* without root. The parameter --user exists in pip to get around this, the more detailed answer is here: https://stackoverflow.com/questions/42988977/what-is-the-purpose-pip-install-user
