[SOLVED] Jupyter Lab doesn't render MathJax equations offline

Jupyter Lab does not render MathJax equations unless I am online and allow access to cloudflare. If I am offline or block cloudflare using noscript then I just get the original markdown. Jupyter Notebook renders equations correctly offline. All packges are installed using pacman (not pip) and are up to date.

This appears to be the same issue as the bug report FS#70150 but the solution there - installing jupyter-server-mathjax - hasn't worked for me. I have tried cleaning and rebuilding Jupyter Lab without success.

The console output of Jupyter Server is:

[I 2021-09-26 21:59:51.640 ServerApp] jupyterlab | extension was successfully linked.

Re: [SOLVED] Jupyter Lab doesn't render MathJax equations offline

Indeed, the extension wasn't actually installed in the package. Should be fixed in jupyter-server-mathjax 0.2.3-2

Re: [SOLVED] Jupyter Lab doesn't render MathJax equations offline

That's fixed it, many thanks arojas.

Edit: forgot to say that I had a "Failed to commit transaction (conflicting files)" pacman error on /usr/share/jupyter/lab/static/2719.35f55731620927420659.js that I resolved by renaming the file
