typescript - Functions higher order with async and await -

compiling following lines tsc

import 'core-js/shim'; import { } 'async'; 

the compiler quits error message:

(...)/npm/node_modules/typescript/lib/lib.esnext.asynciterable.d.ts(32,11): error ts2428: declarations of 'asynciterator' must have identical type parameters.
(...)/npm/node_modules/typescript/lib/lib.esnext.asynciterable.d.ts(39,31): error ts2314: generic type 'asynciterator' requires 2 type argument(s).

node_modules/@types/async/index.d.ts(15,11): error ts2428: declarations of 'asynciterator' must have identical type parameters.
