Answer 1

This might sound silly, but don't name your local variable pusher. The binding of variables in the lambda function happens late, during its execution, and in a scope that you might not be expecting.

I'm not suggesting this is the full answer, but do an import pusher and change to myPusher = pusher.Pusher... to see if the error message changes. If it doesn't, then the problem lies elsewhere.

Answer 2

Adding an empty __init__.py file to the ndg directory fixed this issue.

Answer 3

I would suggest you use virtualenv to keep track of dependencies.

Here is a psedo steps that you may need to make:

 1. virtualenv env
 2. env/bin/pip install <your packages>
 3. cd env/lib/python2.7/site-packages; zip -r mylambda.zip *
 4. also zip your lambda handler 

If you installed everything properly , then zip file mylambda.zip will contain everything you need.
