Django runserver hangs at “System check identified no issues (0 silenced).” for a while

I am not able to start manage.py runserver 0.0.0.0:8000. I am using a MySQL database and I have imported all the required modules. I am trying to run quite basic application.

I am running python 3.7.3 on windows 10. Here is the error I am getting:

System check identified no issues (0 silenced).

MemoryError

I’ve seen a similar MemoryError around here, but I’m not using SQLite and I’ve already tried using DEBUG=False.

Thank you in advance for the help.

Answer

I have just solved my problem by checking my dependencies. I believe that the code was stuck because of some kind of incompatibility among packages.
