Hi,

I have just run the following in my app/functions directory and now get errors when running firebase deploy --only functions

npm install firebase-functions@latest firebase-admin@latest --save

npm install -g firebase-tools

​

The errors I see are;

node_modules/@types/node/index.d.ts:97:11 - error TS2300: Duplicate identifier 'IteratorResult'.

97 interface IteratorResult<T> { }

node_modules/typescript/lib/lib.es2015.iterable.d.ts:41:6

41 type IteratorResult<T, TReturn = any> = IteratorYieldResult<T> | IteratorReturnResult<TReturn>;

'IteratorResult' was also declared here.

Found 2 errors.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
