[Bug] compat/typescript patch does not apply on typescript@4.2.0-beta

• I’d be willing to implement a fix

➤ YN0000: │           var missingFilePaths = program.getMissingFilePaths();

To Reproduce

yarn add typescript@4.2.0-beta (or yarn up); with enableInlineHunks: true in the .yarnrc.yml for the diff printout.

Bonus points: the Playground reproduction fails because the node version is too old.

Environment if relevant (please complete the following information):

• OS: WSL
• Node version: 14.15.4
• Yarn version: 2.4.0

Additional context

The patch applies in older versions of typescript.

From @niieani Sure, create .yarn/plugins/@yarnpkg/plugin-compat.cjs:

module.exports = {
  name: `@yarnpkg/plugin-compat`,
  factory: (require) => {
    // dummy implementation to override the built-in version of this plugin
    return {}
  },
}

Add to .yarnrc.yml:

plugins:
  - path: .yarn/plugins/@yarnpkg/plugin-compat.cjs
    spec: '@yarnpkg/plugin-compat'

You do not imagine how much you saved me time there. I hate the checksum issue I’m getting with these compat patches… And I dont even use PnP :face_exhaling: I read the PR and the Q&A but I have no break by disabling this. Also why not simply check nodeLinker === ‘pnp’ then patch… Well thanks again you saved me a bunch of time with this quick fix 🙂
