@Einlar Thanks for the bug report. It looks like it's throwing an ambiguous error when compiling. Can you help me reproduce the issue? Do you know if there's a block you're trying to render that is causing the issue?

Also, what is your config for katex look like?

I've setup Jekyll following these commands. The error appears with the standard config file (I've only added jekyll-katex to the gemfile and config). I've uploaded all the files here.
Here is the result of "bundle install" and the complete error:

@Einlar I cannot reproduce the issue on my system, which is running on macOS High Sierra. This suggests there's probably an environment pre-req I missed.

Looking at the stacktrace more carefully, it looks like it might be due to a missing Javascript runtime? You can see the supported list of runtimes here.

If you think this might be the issue, could you try adding gem 'therubyracer' to your project's Gemfile/gems.rb then trying again?

linjer avatar linjer commented on May 18, 2024

@Einlar Assuming the javascript engine is the cause. I think I either need to add a javascript engine to the pre-requisites or include an engine (e.g., therubyracer). It's unclear if this is the root cause, but I might want to include an engine directly anyway.

Would love to know if you have any thoughts. Please let me know if you are able to isolate the issue further.

linjer avatar linjer commented on May 18, 2024

@Einlar Since I cannot isolate the issue that is causing the problem for you, without more information, I'm going to close this issue and move forward with a standalone Javascript engine.

If you are still having issues or find any more interesting information, feel free to let me know! Appreciate it!
