Build fails with error ReferenceError: Prism is not defined at Array.forEach (<anonymous>)

I use the freshest installation and make only one change, I add language to prism.

docusaurus.config.js

  prism: {
    theme: lightCodeTheme,
    darkTheme: darkCodeTheme,
    additionalLanguages: ['php'], // <- this is the only change i made
  },

After that, if I try to build the project - it fails with this error:

ReferenceError: Prism is not defined
    at Array.forEach (<anonymous>)
[ERROR] Unable to build website for locale en.
[ERROR] Error: Failed to compile with errors.
error Command failed with exit code 1.

Any ideas how to fix that?

Hey, just published a fix, please try initializing a new project or re-generate your lockfile and let me know if this works

yarn why eval should report using eval@0.1.6 and not eval@0.1.7

Same issue as in https://github.com/facebook/docusaurus/pull/6975
