Failed Manage.py runserver command - django

Question

I'm a beginner in web development. I'm using pycharm and django 2.1 framework
I installed django using ('py -m pip install django==2.1') and it is done.
I started myweb project using ('py -m django-admin startproject myweb .') and it also done
but when I try ('manage.py runserver') command, this is the result:
(venv) C:\Users\مرحبا\PycharmProjects\Myweb>manage.py runserver

AttributeError: 'str' object has no attribute 'insert'
Could you help me please?

Answer 1

In the last line of the error it says
aliases.insert(0, hostname) AttributeError: 'str' object has no attribute 'insert'
Your Aliases variables is a string, not a list, so you can't .insert() to it, as that functionality doesn't exist.
You need to make sure Aliases is a list in your code.
