solution

just add --skipLibCheck params in the CLI

# ✅
$ tsc --skipLibCheck ./test.ts

wait, do you say if you add it in the compilerOptions is doesn't work, but as a command line parameter it does? that would be.... surprising.

that's right.

Your tsconfig is completely ignored when you specify files on the command line instead of -p.

$ tsc --showConfig ./test.ts
{
    "compilerOptions": {},
    "files": [
        "./test.ts"
    ]
}

@andrewbranch without the files key , it's still has that question.

Use --explainFiles to show why every file is included. You cannot prevent the inclusion of files that are included by other files. All of this is working as intended and explained in the docs. If you still have questions after reading them, please ask on StackOverflow or the TypeScript Discord. This issue tracker is not a good place to get support. If you file something here, you need to thoroughly search for duplicates and completely fill out the issue template. Thank you for understanding.
