Zappa crashes when running "zappa"

[cameronk]

Context

After two days and two different OS', I finally got Zappa working. For about 5 minutes, until I had to reset my virtual env (Zappa was packaging my entire virtual env, including /lib/, which resulted in ~100mb deploy zips.)

When I reinstalled, I now get this:

camer@DESKTOP-VRG88TF:/mnt/c/Users/camer/Desktop/Development/ryze/content-engine/api$ zappa
Oh no! An error occurred! :(

==============

Traceback (most recent call last):
  File "/home/camer/.local/share/virtualenvs/api-GJXpcMFr/lib/python3.6/site-packages/zappa/cli.py", line 2610, in handle
    sys.exit(cli.handle())
  File "/home/camer/.local/share/virtualenvs/api-GJXpcMFr/lib/python3.6/site-packages/zappa/cli.py", line 505, in handle

Your Environment

• Zappa version used: 0.45.1
• Operating System and Python version: Python 3.6.3, Ubuntu 16.04.3
• Your zappa_settings.py:

  {
  "dev": {
      "app_function": "app.app",
      "aws_region": null,
      "profile_name": "zappa",
      "project_name": "api",
      "runtime": "python3.6",
      "s3_bucket": "zappa-i38d9iob8"
  }
  }

The same thing is happening to me on OSX with 0.45.1 and Python 3.6.3. I suspect it may be a library issue or something introduced in 3.6.3. This isn't preventing me from using zappa - it's merely an annoyance. Here's my zappa.settings.py:

{
    "dev": {
        "aws_region": "us-east-2",
        "django_settings": "mysite.mysite.settings",
        "profile_name": "default",
        "project_name": "mysite",
        "runtime": "python3.6",
        "s3_bucket": "zappa-a8nviyobq"
    }
}
