python - Not able to install Jupyterlab extensions on GCP AI Platform Notebooks

Question

I have started to experience an issue with installing extensions for Jupyterlab that I have not experienced in the past. I am not able to build after installing new extensions for Jupyterlab.

I am running Jupyterlab with GCP AI Platform Notebooks. I am using the standard Python 3 environment on Debian 10. I have tried to run on different types of machines.

I am receiving a status 500 error. Here is the log from when I run jupyter lab build:

[LabBuildApp] WARNING | Config option `kernel_spec_manager_class` not recognized by `LabBuildApp`.
[LabBuildApp] JupyterLab 1.2.16

An error occured.

See the log file for details:  /tmp/jupyterlab-debug-pnbu3naq.log

Here is the log file with details:

Since I have been able to install the same extensions for Jupyterlab in the past on other VM instances I would expect it has something to do with the version of Jupyterlab that is installed. I would, however, expect that Google would install the latest version of Jupyterlab.

The error log does seem to indicate that it is a permission error, which I don't understand as I am running the jupyter lab build at base. The only setting I have changed after creating the instance is to enable extensions.
