Project must list all files or use an 'include' pattern

Question

I see this warning thrown in VSCode:

This is the line that throws the ts warning:

import packageJson from "../package.json";

Weirdly, building and linting the project works fine:

$ tsc --project .
✨  Done in 1.16s.

$ tslint --config ../../tslint.json --project .
✨  Done in 1.59s.

Is this a warning caused by the VSCode parser, or is there something wrong in my tsconfig.json file?

// tsconfig.json
{
  "exclude": [
    "node_modules"
  ],
  "extends": "../../tsconfig.json",
  "files": [
    "package.json"
  ],
  "include": [
    "src/**/*"
  ],
  "compilerOptions": {
    /* Basic Options */
    "outDir": "dist",
    /* Module Resolution Options */
    "baseUrl": ".",
  }
}

Answer 1

In my case I was builiding a monorepo and referencing one of the packages in another package.

All I had to do was remove composite: true from tsconfig.json and it worked.

Answer 2

Try adding:

"resolveJsonModule": true,
"esModuleInterop": true 

to your compiler options

Answer 3

Add package.json to your includes. It out of src dir.

{ 
    "include": [
      "src/**/*",
      "package.json"
    ]
}

Answer 4

Open your tsconfig.node.json, and add your files path in the includes just like "include": ["vite.config.ts", "yourFilePath"],
