Answer 1

You should install required packages beforehand. Simply install following two packages first.

npm install --save-dev @types/es6-promise
npm install --save-dev @types/es6-collections

Then add corresponding type information to react-native.d.ts file as below.

/// <reference path="../../node_modules/@types/es6-promise/index.d.ts" />

Answer 2

This is how I fixed my problem very similar to this one

inside your tsconfig.json file in the root folder, change:

..."compilerOptions": { "target": "es5", ...

change the es5 -> es6
