Cannot uninstall 'Jupyter' extension. 'Python' extension depends on this.

Environment data

• VS Code version: 1.55.2
• Jupyter Extension version (available under the Extensions sidebar): v2021.5.745244803
• Python Extension version (available under the Extensions sidebar): v2021.3.680753044
• OS (Windows | Mac | Linux distro) and version: Mac 11.2.3
• Python and/or Anaconda version: 3.9.4
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): N/A
• Jupyter server running: Local | Remote | N/A

Expected behaviour

Can uninstall Jupyter without having to uninstall other extensions… notably the Python extension, which I still very much want.

Actual behaviour

When attempting to uninstall, I got the error message in the title and repeated below:

Cannot uninstall 'Jupyter' extension. 'Python' extension depends on this.

Steps to reproduce:

1. Install the Python extension on VS Code
2. Install the Jupyter extension
3. Attempt to uninstall the Jupyter extension

(I confess, I am not sure if this is all that is required. I have been using VS Code with both installed for over a year. But Jupyter started causing problems with the IDE, so I wanted to uninstall it.)

Logs

I have no log for the attempt to uninstall… there is no log, just the dialog box. However, below is a log for the Python extension hanging, for reasons which I think are due to the Jupyter extension not loading properly.

Regardless, I would still like to be able to remove the Jupyter extension without removing the Python extension. It seems that Jupyter should rely upon Python, not vice-versa.

I’m also having all sorts of issues with Jupyter extension, from being too slow to issues with keyboard navigation, diffs not working and so on. The only way to disable Jupyter extension that I’ve found so far is to install Python extension version just before Jupyter functionality was refactored into a separate extension. Click “Install Another Version…” in Python extension and choose 2020.10.332292344 version. After installation, you should be able to uninstall Jupyter extension just fine. It’s also a good idea to disable Jupyter in settings, something like:

    "python.dataScience.disableJupyterAutoStart": true,
    "python.dataScience.useNotebookEditor": false

This worked well for me even at the cost of not having the latest version of Python extension.

It would be great if Python/Jupyter extensions authors consider reversing the dependency so the Python extension won’t depend on the Jupyter one anymore.

It’s actually circular the moment. The jupyter extension depends upon the python extension when starting python based kernels. The python extension depends upon the jupyter extension for some of it’s data viewing features.

We’re unlikely to change this dependency because it’s not really worth the effort (making a 3rd npm module or extension for the dataviewing part). The python extension is however in the process of removing the hard dependency. It should become optional in the near future.
