Warning: Cannot find parent tsconfig.json

Question

I would like to fix the warning:

Warning: Cannot find parent tsconfig.json

in the TypeScript Errors tab in IntelliJ IDEA 2016.3. My TypeScript code lives in the src directory and my TypeScript output is going to lib as expected without the src folder being added to lib.

I consume the lib folder in other projects and it seems to work as expected. So this doesn't seem to be a big problem, but I occasionally have a problem with TSLint where it sometimes does not seem to pick up a .tsx file is JSX and lints incorrectly and seems to occasionally treat it as a normal .ts file. Eventually it seems to figure it out. I am wondering if that is related as my TSLint settings are configured to use tsconfig.json.

I have also previously had .js transpiled files turn up next to the .ts files in the src folder, but not since I modified my tsconfig.json recently.

Files as follows:

tsconfig.json
src/index.ts
lib/index.js
lib/index.d.ts

I've upgraded to TypeScript 2.1.4, but was seeing it with 2.0.10.

My tsconfig.json file:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "jsx": "react",
    "allowJs": false,
    "isolatedModules": false,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "declaration": true,
    "noImplicitAny": false,
    "noImplicitUseStrict": true,
    "noEmitHelpers": false,
    "removeComments": true,
    "noLib": false,
    "sourceMap": true,
    "inlineSources": true,
    "preserveConstEnums": true,
    "allowSyntheticDefaultImports": true,
    "suppressImplicitAnyIndexErrors": true,
    "rootDir": "./src",
    "outDir": "./lib"
  },
  "include": [
    "./src/**/*"
  ],
  "compileOnSave": true,
  "atom": {
    "rewriteTsconfig": false
  }
}

problem is specific to TypeScript version being used (2.1.x); it is fixed in 2016.3. 2 EAP

Note: this answer refers to the issue specific to IDE (WebStorm, PHPStorm, IDEA) version 2016.3: it didn't work well with TypeScript 2.1.x, showing false warnings. If you see similar message (Cannot find parent tsconfig.json) in other IDE versions, it is likely a problem with your configuration: such messages are displayed if currently edited .ts file is not included in any tsconfig.json.
