Minimal repoducible example

💻 Code

Run tsc (yarn tsc, yarn exec tsc, npx tsc, ./node_modules/.bin/tsc) with nodejs flag --experimental-specifier-resolution=node (NODE_OPTIONS="--experimental-specifier-resolution=node" tsc)

🙁 Actual behavior

internal/process/esm_loader.js:74
    internalBinding('errors').triggerUncaughtException(
                              ^

TypeError [ERR_INVALID_MODULE_SPECIFIER]: Invalid module "file:///path/to/project/node_modules/typescript/bin/tsc" 
    at Loader.getFormat (internal/modules/esm/loader.js:117:13)
    at async Loader.getModuleJob (internal/modules/esm/loader.js:242:20)

    at async Object.loadESM (internal/process/esm_loader.js:68:5) {
  code: 'ERR_INVALID_MODULE_SPECIFIER'
}

🙂 Expected behavior

Build without errors

Not, it's not.
This problem because of bin script definition.
Bin scripts defined as

    {
        "tsc": "./bin/tsc.js",
        "tsserver": "./bin/tsserver"
    }

And when I call yarn tsc, nodejs trying to run node_modules/typescript/bin/tsc. This file hasn't extension and nodejs throws an error.
Why it works in Jest?
Because it use another bin declaration like this:

{
"jest": "./bin/jest.js"
}

For package manager, this script has link with name jest, but nodejs run jest.js, file with extension.
So, solving my problem is adding .js in bin files and in paths in package.json bin. It won't change behavior for exists project by help projects with configurations like mine.

As you can see, another experimental flags for native modules aren't change behavior (Now I run tsc without --experimental-specifier-resolution, but with all another flags in scripts and it works)
