[Migrated] zappa package with slim_handler=true doesn't include Werkzeug package (introduced v0.46.0)

[jneves]

Originally from: Miserlou/Zappa#1547 by sheats

Context

I thought I was running into issue #64 but turns out I found a regression introduced in v0.46 related to how the handler_venv is packaged and uploaded when using slim_handler.

I created a small repo to show the problem: https://github.com/sheats/zappa_issue
If you keep zappa==0.46.0 (or 0.46.1) in requirements.txt and deploy the function the only thing that prints in the logs is:

Unable to import module 'handler': No module named 'werkzeug'

If you change requirements.txt to zappa==0.45.1 and update the function the problem goes away.

When I unzipped the handler venv zip after running zappa package I only see the following:

drwx------   9 user  staff    288 Jun 25 06:27 .
drwxr-xr-x  16 user  staff    512 Jun 25 06:27 ..

-rw-r--r--   1 user  staff    467 Jun 25  2018 zappa_settings.py

Expected Behavior

I expect the logs to show other errors or normal successful logs.

Actual Behavior

handler.py tries to import werkzeug on line 17 but fails because Werkzeug wasn't included in the handler_venv zipped package.

Possible Fix

Don't know the code well enough to come up with a fix strategy yet.
