3 years ago I'm having the same problem. I also tried to reinstall the whole anaconda. Those failed extension files are not in my system but they still showed up in the list and able to work in the Jupyter notebook. I am also really wondering if there's a way that I can remove them. Thanks!
I am a new developer and I want to create a small extension for jupyter notebook. I wrote the essential files and put my extension package under the nbextensions directory, then I ran the command "jupyter contrib extensions install --user" to install my extension. Then I restarted the notebook and wanted to check if my extension works normally, but unluckily the extension didn't work normally. So I decided to remove that from the "Nbextensions" list and modify my codes. I tried many ways to remove that including "deleting all my failed extension files" and "reinstalling the nbextension", but the failed extension is still in the list. I do not know how to remove that. And do you have better ways to test when you create a new extension? Thanks.
