Hi,
I am trying to install extensions to Jupyter Lab on my Mac but it always fails to build.
Example with jupyterlab_variableinspector
I directly installed the extension on Jupyter Lab and then clicked on build.
I got this error message:
Build failed with 500, please run 'jupyter lab build' on the server for full output.
Therefore, I ran jupyter lab build on my terminal and it fails to build as well.
Error message from my Terminal

> If you are building via the `jupyter lab build` command, you can disable

Do you have any idea how I could fix this issue ?
Thank you.
I would try to uninstall the source version of the extension with:
