Protractor - The 'files' list in config file 'tsconfig.json' is empty. (18002)

Question

I want to implement e2e in my Angular v5.x project using protractor.js. But when I run the command

ng e2e -s false

I'm getting this error below can anyone tell me how do I fix this?

[15:58:11] E/launcher - Error: TSError: ⨯ Unable to compile TypeScript

Here is my tsconfig.json (which is located inside e2e folder)-

{
  "compileOnSave": false,
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "commonjs",
    "moduleResolution": "node",
    "outDir": "../dist/out-tsc-e2e",
    "sourceMap": true,
    "target": "es5",
    "typeRoots": [
      "../node_modules/@types"
    ]
  }
}

Using the "files" property. Hope it helps you.

{
    "compilerOptions": {
        "module": "commonjs",
        "noImplicitAny": true,
        "removeComments": true,
        "preserveConstEnums": true,
        "sourceMap": true
    },
    "files": [
        "core.ts",
        "sys.ts",
        "types.ts",
        "scanner.ts",
        "parser.ts",
        "utilities.ts",
        "binder.ts",
        "checker.ts",
        "emitter.ts",
        "program.ts",
        "commandLineParser.ts",
        "tsc.ts",
        "diagnosticInformationMap.generated.ts"
    ]
}
