[Bug] Resolve error: unable to load resolver "node" import/named with ESLint configured

[IT-CASADO]

• I'd be willing to implement a fix

Describe the bug

I try to use Yarn 2 together with ESLint and Prettier, but I get this error:

Resolve error: unable to load resolver "node" import/named
Resolve error: unable to load resolver "node" import/no-extraneous-dependencies
(and five more errors)

To Reproduce

Clone this git repository: https://github.com/IT-CASADO/yarn-eslint/tree/yarn-v2
(master branch contains the same configuration with Yarn 1)

Execute following command: yarn eslint ./src/.

Environment if relevant (please complete the following information):

• OS: [Windows]
• Node version [12.17.0]
• Yarn version [2.0.0-rc.33]

Additional context

I followed this steps here:

• https://yarnpkg.com/getting-started and
• https://yarnpkg.com/advanced/editor-sdks

I'm assuming no configuration errors with ESLint, because it is working with Yarn 1.
Do I miss something special for Yarn 2?

Yarn 2 is stricter - see https://next.yarnpkg.com/features/pnp#pnp-loose-mode

Enabling loose mode temporarily and running outputs:

(node:34285) [MODULE_NOT_FOUND] Error: eslint-module-utils tried to access eslint-import-resolver-node, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Resolve by adding a hint to .yarnrc.yml

packageExtensions:
  eslint-module-utils@*:
    dependencies:
      eslint-import-resolver-node: "*"

I migrated from yarn v1 to v2 and it i get the authors error on all my dependencies.

Do I have to add each one of them manually now - but also in the future?

Only if you want to keep using PnP, which you can disable.

You can resolve the resolver manually in your eslint config to fix the resolution

module.exports = {
	settings: {
		'import/parsers': {
			[require.resolve('@typescript-eslint/parser')]: ['.ts', '.tsx', '.d.ts'],
		},
		'import/resolver': {
			[require.resolve('eslint-import-resolver-node')]: {
				extensions: [<extensions here>],
			},
		},
	},
};

packageExtensions:
  eslint-module-utils@*:
    dependencies:
      eslint-import-resolver-node: "*"

This works for executing yarn eslint, but for CRA the error still remains if I try to start the app. It makes it impossible to start. Any solution for CRA?
