I am getting and error as - Module ''selenium-webdriver'' has no exported member 'Promise', while trying to run protractor tests in webstorm

Below is the error I am facing.. the same code is working when I compile it to JavaScript here "compile Typescript to JavaScript". I would like to execute it without generating the JavaScript files. Below is the code snippet.

getIndusElem(): Promise<string> {
    return element(by.id('industry')).getText()
  }

Thanks in advance for your help...
