Description
El error se puede generar presionando "Ctrl + S" para recargar Django y no es necesario realizar algún cambio en el código para obtener el error que parece ser aleatorio. Por lo pronto lo solucioné regresando a Django 2.1.4
Algunas veces funciona bien e informa lo siguiente:
System check identified no issues (0 silenced). April 11, 2019 - 19:29:25 Django version 2.1.4, using settings 'base.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.
En ocasiones pasa lo siguiente y es muy repetitivo:

Everything works for me :| Can you provide test project to reproduce this issue?

In my case, it seems that somehow one or more of the '.pyc' files in my venv had gotten corrupted somehow. I deleted all the '.pyc' files in my venv and now I can no longer reproduce the problem.

I got the same issue. I tried to delete all .pyc. However, the problem still exists.
I'm not sure what the problem is.

There is no resolution for this issue yet. The issue is still there and cannot be easily reproduced.

FWIW, I'm seeing this error too. It happens to me after code has been changed and it's trying to reload, likely while a request is being served. I'm running the default dev server, django 2.2.3, on python 3.7.1.
comment:13 by , 5 years ago
I, too, had this exact same problem. It was the result of having pyc files that were out of date. The problem bit us specifically in the context of a rebuild in a docker container. Simply removing the pyc files made this go away. I know it sounds unlikely, but it's true. I hope that helps.

See https://github.com/encode/django-rest-framework/issues/7078
Upgrading django-rest-framework to >= 3.11 should mitigate this.
Thanks for the report, however I cannot reproduce this issue. You should take into account that not all 3rd party packages that you mentioned in a ticket description support Django 2.2, e.g.
django-environ.Please use one of support channels.
