Answer 1

Core-js did not work for me as it caused other issues, however, simply installing the latest version of npm i @types/es6-promise --save-dev got rid of the issues. The issues for me stemmed from compiling an sdk that was using rxjs. Here is the error I was getting:

`node_modules/rxjs/Observable.d.ts(59,60): error TS2693: Promise only refers to a type, but is being used as a value here.`
