MongDB cannot find type definition for Promise

Question

I created a new project, installed several type definitions (from DefinitelyTyped) and made a base src/go.tsfile.

Whenever I port the code, I get a ton of errors TS2304: Cannot find name 'Promise'!
./typings/mongodb/index.d.tsrefers to Promise, but the compiler does not seem to find this.
Please note: I also installed dt~promise.

Screenshot (Errors on the left side, installed type definitions and application code are on the right)

Content typings.json:

{
  "globalDependencies": {
    "dotenv": "registry:dt/dotenv#2.0.0+20160327131627",

  }

Any thoughts?
