Firebase-functions: @google-cloud/storage package and typescript 2 error

[galki]

just by installing @google-cloud/storage and running npm run build i got the following error:

node_modules/google-auth-library/build/src/auth/oauth2client.d.ts(291,55): error TS1039: Initializers are not allowed in ambient contexts.

fixed by updating typescript (from 2 to 3) and tslint packages... perhaps it was just the reinstall but can we get firebase functions to initialize with typescript 3 from the start?

_firebase-tools version:_ 6.0.1
_os:_ windows 10

I had the same issue. However, I did have typescript 3+ installed. Updating the tslint from 5.8 to 5.11 fixed the it for me.

I think, this issue should be closed.
