MathJax Plugin Issue: “Could not find module discourse/lib/load-script”

The MathJax plugin is broken in a Discourse installation, displaying the error “Could not find module discourse/lib/load-script” TopherTheGeek. The issue occurred after upgrading to Discourse 1.2.1 and MathJax 0.4.1.

TopherTheGeek attempted various fixes, including updating, disabling and reenabling the plugin, rebooting, and rebuilding the app, but none were successful.

sam suggested that the issue is due to MathJax depending on the latest stable Discourse version. sam later clarified that the user should be on the “tests-passed” version, not the stable version.

rking recommended using the beta version, which has the required dependencies.

TopherTheGeek confirmed that switching to the beta version fixed the issue.

In my installation of Discourse, MathJax is broken. I think that’s probably due to “Could not find module discourse/lib/load-script”. Things were working, and I cannot be sure when they broke, but I suspect it happened when I upgraded to Discourse to 1.2.1 and MathJax to 0.4.1.

This is the full error message I’m seeing with Chrome:

To fix this, I tried:

  1. Double checking I’m up-to-date on everything.
  2. disabling and reenabling the MathJax plugin.
  3. Rebooting, naturally.
  4. launch app rebuild

What else might I try?

I think the install is pretty standard. I followed the instructions to install with Docker on DigitalOcean from before the 1.0 release, and I’ve always upgraded via the Admin panel since then.

If needed, the issue can be seen here.

MathJax now have a dependency on latest stable Discoruse.

Either, move to tests-passed

Or, in the container definition pull an old version of mathjax, or fork it, or ask mathjax maintainers to introduce a branch for old.

Now I’m confused. I’m on Discourse 1.2.1, and my dashboard says that I’m up to date. Do you mean that 1.2.1 is not the latest stable version?

Sorry, I mixed up my terms:

https://meta.discourse.org/t/release-schedule-post-version-1-0/17694

you want to be on tests-passed.

I think that beta has the dependencies he needs.

That fixed it. Thanks Sam!
