28174	Cannot run `manage.py runserver` on Windows with quotation mark in .env file (TypeError: environment can only contain strings)	Paul Mestemaker	Mark Rogaski	"We have a .env file with a SECRET_KEY defined as follows
SECRET_KEY=""SECRETKEYHERE""

This causes a failure with Django 1.11. The workarounds are:
1) Downgrade to Django 1.10
2) Remove the quotation marks and just have SECRET_KEY=SECRETKEYHERE

This appears to only be a problem on Windows and does not repro on Mac/Linux.
