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 into another package.

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

Answer 2

As dumb as it sounds, restarting VSCode fixed this for me.

Answer 3

Samuel's suggestion works great for me.

I got the same error for another reason, I use .json files as static mocks for tests - importing them as modules. In my case the files are nested inside src, and adding an explicit pattern to include .json files did the trick for me.

Here's the relevant part in my tsconfig.json:

{
  "include": [
    // ...other includes
    "src/**/*.json"
  ]
}

Referring to the question asked - this should work:

{
  "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"],

Answer 5

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

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

Answer 6

This can happen if your server is running when you add new files. If this is the case, simply stop it and start it again so that is can rebuild and include the new files.

Answer 7

Try adding:

"resolveJsonModule": true,
"esModuleInterop": true 

to your compiler options

Answer 8

On WebStorm

After including the file in tsconfig.app.json, I also had to do "File" > "Invalidate Caches and Restart" before the error went away.

EDIT: Sometimes it's enough to just restart the Vue Language Server (at the bottom right)

Answer 9

There's an incredibly long thread about this issue in the TypeScript repository.

Although not a permanent fix, the easiest solution is restarting your TypeScript server.
