When I follow the steps, I got errors

[supernow]

../../../usr/local/lib/node_modules/typescript/lib/lib.d.ts(1336,11): error TS2428: All declarations of 'Promise' must have identical type parameters.
../../../usr/local/lib/node_modules/typescript/lib/lib.d.ts(1343,211): error TS2314: Generic type 'Promise<T, R>' requires 2 type argument(s).

How can I solve it?
