Open Jupyter in VSCode: TypeError: Cannot read properties of undefined (reading 'makeSettings')

Question

System: MacOSX 10.15, VSCode Version: 1.67.2, Python Kernel Version: 3.8.13 (Conda base).

I created a new Jupyter notebook in my VSCode using command shortcut and selected the right python kernel showed above. The empty notebook page is well loaded and no error message occurred.

But when I typed and ran any code in the cell, this error message showed up below the cell.

Then I clicked the "log" link and the error log showed up and it was like this:

And hence I couldn't run any code in the notebook cell. Then I changed to another Python Kernel (3.9.12) of the same notebook, it showed the same error message:

Please give me a solution to overcome this bug.

Update: I tried to reinstall pyzmq to an older version in the canda base environment and it didn't change anything. Then I typed command jupyter --version and everything is well installed.

Update: I have searched on Github Issues of VSCode. There are two similar issues that are all caused by some extensions, one is called "Gitduck"(now renamed "duckly"), the other is "nur.Script". The link to these issues are here:

Cannot read property 'makeSettings' of undefined #834

Cannot read property 'makeSettings' of undefined #128458

But unfortunately, I never have installed any of these extensions in my VSCode. So it may be caused by a similar extension but I still don't know the name.

Finally, I use the command code --list-extensions to list all my installed extensions here, maybe helpful for filtering which extension is the bad guy:

Final Update: Today (05/31) I opened VSCode and tentatively created an empty Jupyter notebook, and this problem has gone away. I have done nothing, maybe VSCode's auto-update has solved this problem. Case closed.

Answer 1

You can try reinstalling the pyzmq module.

pip uninstall pyzmq
pip install pyzmq==19.0.2

Hope this helps you.
