Answer 1

In my case the Bluebird folder was called 'bluebird' and i was importing it as 'Bluebird' (with a capital 'B') so i changed the import string to be 'bluebird' (im working on linux).

Hope this helps someone.

Answer 2

You might need to install the bluebird package locally. Try

npm install --save bluebird
