Trouble Running manage.py runserver for CentOS 8 (Python 3.6)

[jessiebryan]

I tried to install this on a CentOS 8 and ran into a few minor issues that I was able to work around (namely how virtualenv is created).

Now I am having an issue when launching the service - I have a traceback:

Performing system checks...

Any feedback on this would be great, thank you!

Hello. This error was fixed in master.

[jessiebryan]

Thanks! - I am no longer having that traceback. The server is running and returning "Server Error (500)"

Where can I get more detail about its issue? I manually invoked the daemon and watched my browser connect but there are no errors to console/stdout.

[larrabee]

You can set Debug = True in settings.py. It's enables stack traces.

Hey,

I get a 500 Error because of this: 'dict' object has no attribute 'iteritems'

Python 3 removed the function iteritems. Instead they added items.

I tried that locally and its showing the website now.

According to this https://stackoverflow.com/a/39432244, the items function also works in python2 (its just a but slower).

[larrabee]

Eah, forgot commit this change. Thanks for feedback ;)

The website is loading now, Thank You @larrabee and @asohh for the assistance.
