Django & Migrate Error: I can't migrate my project - django

I was trying to run a Django project which I got from someone else.
But I can't do the migration.
I came from a mobile app development background. So I'm quite new to this backend thing including Django.
Please have a look and help with this issue. Thank you

ModuleNotFoundError: No module named 'bootstrap4'

Bootstrap is a dependency you need to add. You can install it by running the below command before migrating.(This is a one time setup)
python -m pip install bootstrap4
Since you mentioned you got the project from someone else.In that case check if there is a file called requirements.txt.
If it exists, run the below command from that directory to install all the required dependencies.
Python -m pip install -r requirements.txt

ModuleNotFoundError: No module named 'allauth'
I did setup a virtualenv and installed django-allauth with pip and i followed the install instructions from the django-allauth docs. I fail to see where this error is comming from, any help would be greatly appreciated.
Install the library first. In your console:
pip install django-allauth

Django INSTALLED_APP Resolving to "ModuleNotFoundError"

The pip module Im using needs to be included in installed apps as such:
INSTALLED_APPS = [
...,
'django_apscheduler',
...
]
But I keep getting the following when I build my app:
ModuleNotFoundError: No module named 'django_apscheduler'
Even though the app is clearly listed in my pip list. The module in question is Django APScheduler.
EDIT: Ive already installed the module via pip install django_apscheduler, but it is listed in pip list as:
django-apscheduler # using - as opposed to _
EDIT 2: Full trace:

this error happens when you have NOT installed the app.
run pip install django_apscheduler and try again.
make sure you are installing it in your python environment or in your appropriate virtual environment

ModuleNotFoundError: No module named 'django_pg'
It looks like you forgot to do pip install django-pgfields to install it.
However, you probably shouldn’t be using this package. It hasn’t had any updates for years, so won’t support modern versions of Django.
Since Django 1.8,
Django comes with django.contrib.postgres, which might provide the Postgres functionality that you require.

The same thing happened to me. I just exec pip install channels and it worked.

Django 1.7 Migrations

I am using django 1.7 and I just added a custom user model. When I run either python3 manage.py makemigrations or python3 manage.py migrate I get the error: TypeError: __init__() got an unexpected keyword argument 'preserve_default'. This issue came along after adding the new custom user model. The complete traceback is:

Django 1.7.1 added support for the preserve_default param in AlterField. Therefore an upgrade of Django from version 1.7 will resolve the issue.
pip install django --upgrade
python manage.py migrate
Had the same problem. I solved it with:
pip install django --upgrade
python manage.py makemigrations
python manage.py migrate
Why exactly it gets solved like that, I dont know, someone with deeper knowledge might be able to explain...
pip install "django<1.8" -U
then run migrations.... If you update without versioning you'll end up with another active trunk and it's not what you want.
I met the same problem. and I found my Django version is 1.7.0.
After running pip install django --upgrade, my Django version changed to 1.7.4, and the problem is gone.
I remember the other computer that sync the projects files with this one through Internet, has Django version 1.7.3. So I come to the conclusion that this problem is caused by inconsistent versions of Django.
