Answer 1

Typescript add resolveJsonModule in version 2.9 but you are using typescript 2.5.3 ( official doc ).

Typescript add esModuleInterop in version 2.7 ( official doc ).

As Typescript 2.9 is used from Angular 7, I don't know if you can update Typescript.

Maybe try another way like in this answer .
