Bug Report

After upgrading to ^5.0.0, when extending a NPM tsconfig.json and running tsc --noEmit --skipLibCheck, I get a `File 'tsconfig.json' not found.

🕗 Version & Regression Information

Without any other changes, my configuration in 4.9.5 works and passes as expected. Moving to 5.0.2 and the error occurs.

"Bugs" that have existed in TS for a long time are very likely to be FAQs; refer to
https://github.com/Microsoft/TypeScript/wiki/FAQ#common-bugs-that-arent-bugs

If possible, please try testing the nightly version of TS to see if it's already been fixed.
For npm: typescript@next
This is also the 'Nightly' version in the playground: http://www.typescriptlang.org/play/?ts=Nightly

  "compilerOptions": {
    "jsx": "react",
    "baseUrl": ".",
    "outDir": "./dist",
    "lib": ["es6", "es2017", "es2020", "es2020.promise", "esnext.asynciterable", "DOM"],

  },
  "exclude": ["dist", "node_modules", "./cypress", "./i18n", "./publish", "./secrets"],
  "include": ["./*.ts", "./*.tsx", "./src/**/*.ts", "./src/**/*.tsx"]
}

🙁 Actual behavior

In 5.0.0+, the following command fails:

$ tsc --noEmit --skipLibCheck --excludeDirectories ./i18n
tsconfig.json:2:14 - error TS6053: File '@internal-library/tsconfig.strict.json' not found.

2   "extends": "@internal-library/tsconfig.strict.json",
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error in tsconfig.json:2

🙂 Expected behavior

As happens in 4.9.5 and before, the following should succeed:

$ tsc --noEmit --skipLibCheck --excludeDirectories ./i18n
✨  Done in 7.59s.

Very likely a duplicate of #53314. If not, please post the relevant contents (package.json, tsconfig path, etc) of @internal-library

@RyanCavanaugh Sorry, you are right. These seems to be a dupe. I'll follow #53314
