You're using the staticfiles app without having set the required STATIC_URL setting – Django

I have 5 months of experience in django and I can not just find the solution of the error which I encounter.
I think it depends on frontend files, I can not deal with static files right now
Recently, I have been building a chat app called PyChatt

Whole project available on Github here

traceback:
