Using jupyter labextension manager to install jupyterlab-recents gives error, but conda install works?

[richlysakowski]

Description

I wanted to install the package "jupyterlab-recents" the same way that I installed the package "jupyterlab-code-snippets"

The following command WORKED for "jupyterlab-code-snippets" using the jupyter labextension manager, but not for "jupyterlab-recents".

C:\Users\PowerUser\Desktop>jupyter labextension install jupyterlab-code-snippets
Building jupyterlab assets (production, minimized)

However, the following command failed with a jupyterlab-recents version error

C:\Users\PowerUser\Desktop>jupyter labextension install jupyterlab-recents

Then I tried the conda install -c conda-forge jupyterlab-recents and IT WORKED.

HERE IS THE RESULT:
C:\Users\PowerUser\Desktop>conda install -c conda-forge jupyterlab-recents

I don't understand why the approach using "jupyter labextension manager" did not work.

HERE IS THE OUTPUT using "jupyter labextension manager"

Reproduce

Type the command:

C:\Users\PowerUser\Desktop>jupyter labextension install jupyterlab-recents

Here is the result:

[fcollonval]

This project is a fork of the original extension. The consequence is that the NPM package (the one used when running the command jupyter labextension install <package_name>) has a different name: @jlab-enhanced/recents.

The consequence is jupyter labextension install jupyterlab-recents is installing an older version.

That said, I highly discourage using jupyter labextension install for JupyterLab >=3. You should prefer the pip installation or conda installation.
