I have Django 1.4.1 and Python 2.7 installed from ports on Mac OS X 10.7. When I try to run manage.py runserver 8000, I'm getting an error:

What's this, and how to fix it?
I don't know why you think this has something to do with MacPorts. The traceback shows the error, which is in line 41 of PyCartApp/models.py: you've put models.Model(max_length=128) where I presume you meant to put models.CharField(max_length=128).

I'm following this tutorial to experiment Channels with Django. I'm working on Windows 10 HOME, Django 2.1.4 and Python 3.7.1
The goal of this tutorial is to build a chat app.
After downloading chromeDriver and adding it in the PATH, I run this command in my prompt :
py manage.py test chat.tests
Which returns this error message :

How can I solve this problem? Many where we recommend that you sudo easy_install pip the team, but it did not help.
Are you sure that the name of the widget class is correct?
I was checking django-redactor and django-redactoreditor and they don't have a class named "JQueryEditor".
I have a django project working fine . now i need to add login with session on that project I use mango .
As added in setting.py file
SESSION_ENGINE = 'mango.session'
then it started to give following error:

how I can solve this ?
and is there is any other method should i try for login with session ?

Running all tests with ./manage.py test works. This exception occurs only when trying to run single test or test class. However running all tests takes too much time so I want a way to run single test.
Application and django admin works too. There's no __init__.py in root directory of the project.
Suddenly discovered that problem is caused by django-debug-toolbar. Removing it from the project solved this issue.
There is possibly duplicate of this question with similar problem also caused by django-debug-toolbar.
This was the traceback, please help.

BeautifulSoup is not a Django-app. Its a python package/module. You don't have to add to INSTALLED_APPS. It just need to be available in your PYTHONPATH to use it.
Your traceback doesn't give clue what is actually wrong with your Django project.
The only time you ever need to do a syncdb is when you have to do something to the db. BeautifulSoup does not need to use the db at any point and does not need to be an installed app
