This error introducing due to TypeScript compiler is not enabled in your IDE. you need to enable TypeScript compiler.

Enable Typescript compiler in Webstorm:

go to Webstorm menu(upper left menu) => Preferences menu => Languages & Frameworks => click on TypeScript => Enable Typescript compiler(enable checkbox) => enable Use tsconfig.json option => click Ok button and you are done.
