The whole error is quite huge :

I just generated the project and didn't do almost anything. The program works on my computer but not on my friend's. We have the same versions of python/django etc.

Django - After installing "Bootstrap4" with pip, got syntax error on settings.py

After installing "Bootstrap4" using pip, add tags in html files, and adding it in requirements.txt and settings.py, do migrate but it shows this:

vaccinations = models.ManytoManyField('Vaccine', blank=True)
**AttributeError: module 'django.db.models' has no attribute 'ManytoManyField'**
Can anyone let me know what I am doing wrong?

The t needs to be capitalized in the ManyToManyField portion, Also Vaccine should reference a model
if it's in a different models.py.
from [Appname].models import Vaccine
vaccinations = models.ManyToManyField(Vaccine, blank=True).

Why am I getting this: ImportError django.contrib.auth: No module named 'pylibmc'

Attempting to deploy to a virtualenv on Ubuntu 13.10 VPS ... running Python 3.3.2 and I can't figure out how to resolve this.
I tried doing a "pip install pylibmc" but that just blew up (I think because pylibmc does not support Python 3), but I'm not really sure.
Anyhow, can someone explain why I'm getting this message and how I can resolve the issue given my setup?
