MathJax fails with newest version of Discourse? v1.9.0.beta4 +145

Hi,

I ran into an error:

Uncaught TypeError: Cannot read property 'inlineBetween' of undefined

MathJax does not work with Discourse, probably due to this file:
https://github.com/kasperpeulen/discourse-mathjax/blob/6b7ca800de53a424f52cb2ea36d8ee9ee0c0470f/assets/javascripts/tex_dialect.js

Discourse Version: v1.9.0.beta4 +145
MathJax repo: (from app.yml)

git clone https://github.com/kasperpeulen/discourse-mathjax

Not sure why... for now.

https://github.com/rux-pizza/discourse-mathjax - fixed here.

you mean https://github.com/rux-pizza/discourse-mathjax can fix this problem?

But I tried and still not working. Do you have more solutions?

20170723, I found it working. Don't know why, just install https://github.com/rux-pizza/discourse-mathjax is OK.

I'm having the same problem. How exactly did you guys make it work?

I added the git clone https://github.com/rux-pizza/discourse-mathjax.git line in app.yml then did a ./launcher app rebuild but my posts are still bare. I tried a rake posts:rebake to no avail.

Before this I tried the newer Math plugin which works with v1.9 but doesn't support many features. I'm trying to go back to the mathjax plugin but have so far been unsuccessful.

Got it ... I had to disable the newer math plugin by commenting it out in app.yml then did a ./launcher app rebuild followed by ./launcher enter app and rake posts:rebake. Leaving this here in case others have the same problem.

The original plugin repo loads a file meant for adding compatibility with older Discourse versions, and this file calls functions which are no longer available in v1.9, hence it fails. This is good to know for the future as it allows a quick manual fix for newer Discourse versions ... hopefully.
