title: ts An async function or method in ES5/ES3 requires the 'Promise' constructor
body: <p>Hello I'm Using async/await in my TypeScript Project, But I Get this log:</p>
  
  <p><em>[ts] An async function or method in ES5/ES3 requires the 'Promise' constructor.  Make sure you have a declaration for the 'Promise' constructor or include 'ES2015' in your <code>--lib</code> option.</em></p>
  
  <p>How Can I Solve That?</p>
