问题
I'm building a little Django REST API. I've configured a separate settings module for local and production but I'm having an annoying error which is:
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.
This error doesn't make sense because I have the SECRET_KEY variable set. Here are my base.py (which is my base settings for the API) and the local.py. Also, here are my wsgi.py and manage.py.

django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.
回答1:
Most probably you have an env variable SECRET_KEY set to an empty string. Check if this is the case:
$ env | grep SECRET_KEY
SECRET_KEY=
If this is what you get, then you have probably tried to clear the env var by issuing
$ export SECRET_KEY=
This will not remove the variable, but instead set its value to an empty value. To remove the variable, issue
$ unset SECRET_KEY
Verify the variable is removed by issuing env | grep SECRET_KEY again, this time the output should be empty.
回答2:
from django.conf import settings
You shouldn’t be importing settings inside settings. Remove the import, and use SECRET_KEY instead of settings.SECRET_KEY
回答3:
In case anyone else ends up here. For me the issue was that I was running the local run server through PyCharm.
PyCharm sets the setting module as an environment variable over riding your manage.py file. To fix this I had to open the run configurations and edit the Environment variables.
Just check that your IDE isn't doing anything sneaky if you're having trouble with the settings file.
