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 Intell

Answer 1

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.

Answer 2

Try to set the "version number" to your tsconfig.json file.

{
    "version": "2.1.4",
    "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
    }
}

Answer 3

Try setting up include section in file tsconfig.json like in below image.
(Note that my project's root folder is frontend and my include section is frontend/**/*).

Of course you don't need to rename your project's root folder to frontend.
Only the naming should match.

It should take effect immediately after you save the tsconfig.json and open a .ts or .tsx file. If it doesn't try restarting the WebStorm/IDEA.

And don't forget to clear the error console before testing this solution. It might cache the previous messages.

P/S: I'm using WebStorm 2016.3.1.

If you were using webpack together with ts-loader the above solution would cause your builds to fail. If that was the case consider this approach instead.

Answer 4

None of the above solutions worked for me, but I did stumble onto a tsconfig change that did. It seems the IDE is using different rules that tsc.

This did NOT work:

"include": ["./typings", "./src", "./test"],

This did work:

"include": ["./typings/**/*", "./src/**/*", "./test/**/*"],
