In the Windows node environment, the module cannot be loaded

[xiazhongda]

Environment：Nodejs 24,windows 11
mathjax Version：4.0.0 and 4.1.0
Error ：Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs.

I can solve the problem using the code below, but I'm not sure if it's because I'm using MathJax incorrectly. Could you give me some hints?

import {pathToFileURL } from 'node:url'
await MathJax.init({
  loader:
    { 
      load: ['input/tex', "output/svg"] ,
      require: (file => import(pathToFileURL(file))),
    }
  }
});

I thought I had taken care of that in 4.1.0, but apparently not.

What you have done is probably fine, but perhaps easier would be to use

await MathJax.init({
  loader:  { 
    load: ['input/tex', "output/svg"] ,
    paths: { mathjax: 'mathjax' }
  }
});

(or mathjax: '@mathjax/src/bundle' if you are installed the @mathjax/src package rather than mathjax).

I will need to make a PR to fix that in the next release.
