Can't run a specific django project in a virtualenv

I need to edit but first run this project: https://pagure.io/fedora-commops/fedora-happiness-packets and it gives me errors even though I followed the instructions.
First I forked the repo, then cloned it to my computer and I followed the instructions listed in the setup section of the README.md file. When I run the command ./manage.py collectstatic I get this error:
Traceback (most recent call last):

ImportError: No module named celery
I tried importing celery but that method didn't work and I don't want to mess with the project.

Looking at issue 49, it looks like celery is a dependency but it isn not listed in the requirements. Until that is fixed, you'll have to install it manually.
pip install celery

Have you done pip install -r requirements in the virtualenv ?

Django - running manage.py produces fatal error for version.py: Not a git repository

I have copied my Django 1.4.3 app from one server to another. It is running using mod_wsgi daemon on the other server.
mod_python is installed, as verified by looking at php.info(). Python version is 2.7, and Apache version is 2.4.
I get the following error whenever I run manage.py runserver 0.0.0.0:8000:

The app requires python 2.7, and I don't know how to reset mod_python to something that's compatible with version 2.7.

Cloning a heroku hosted django project to your local machine

I'm new to python, Django, heroku and even PostgreSQL but am working on a Django project with a team of 3 devs (they set it up), so I'm trying to set it up on my local machine so I can start developing.
Firstly I cloned the repository to my local machine, there was a requirement.txt file, so I ran pip install -r ./requirements.txt to install all the python packages the project uses. Theres a runtime.txt file which specifies python 3.5 so I need to upgrade that. I see that gunicorn is one of the packages in requiments.txt, so I'm guessing I need to use that as the web server.
Heres the packages in requirements.txt that look important to me:
Django==1.9.6
gunicorn==19.5.0
psycopg2==2.6.1
boto3==1.3.1
boto==2.40.0
whitenoise==3.2
django-extensions==1.6.7
The site also has a .buildpacks file, which seems to be a heroku specific thing:
https://github.com/a2ikm/heroku-buildpack-libjpeg62
https://github.com/heroku/heroku-buildpack-python
https://github.com/rafaelp/heroku-buildpack-wkhtmltopdf
Theres a Procfile that contains this:
web: gunicorn myproject.wsgi --log-file -
worker: celery worker --app=genome.tasks.app -l info --beat
I'm wondering what the best way to do this is. Is there a way to automatically generate a virtual environment that has all the requirements and software specified in the project? I'm already using a virtual dev environment with created with Vagrant so I could provision it with all the dependencies, but I get the feeling theres a better way to do this.
UPDATE:
Heres what what happens when I try to run the server with python manage.py runserver:
$ python manage.py runserver
Current environment: P

SyntaxError: invalid syntax
I'm guessing the parse error is due to using python 2.7 in a project that uses python 3.5. I installed python 3.5 with sudo apt-get install python3-all. Trying the same thing with python3:
$ python3 manage.py runserver
Traceback (most recent call last):
File "manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named 'django'
> python3
The second error means the packages I installed with pip install requirements.txt, they were installed for python 2.7, not 3.5. So this is obviously where virtual environments can come in. I tried this sudo -H virtualenv -p /usr/bin/python3 py3env, both with and without sudo, and both times I got errors :

I came across this thread:
protocol error setting up virtualenvironment through vagrant on ubuntu
Where someone was having this problem using virtualenv inside a vagrant VM, and a possible solution is setting up the venv outside of the shared vagrant folder.

Django, cannot make messages

I'm writing this post because after hours of research around, no real solution was found about my issue.
I've a Django project that used to run on another computer. Now, I've a new one, I've reinstalled Django and VirtualEnvWrapper.
I've cloned my project from my git and I can work and deploy without any issues.
Running ./manage.py works when I'm on the correct virtualenv (via workon 'my_project_name').
My problem is that I can't generate translations any more.
Here is the trace-back:

Django/Celery can't find importlib

So I just updated django to 1.2.3 and now when I try to run 'python manage.py shell' to work in the django environment, I'm getting the following error.

ImportError: No module named importlib
Any ideas. I can't seem to find what's going on here and for all I can tell I'm running the same versions on my web server and I don't have the same error showing up.

importlib which was added in Python 2.7/3.1, I believe. You can download a port for pyton 2.5 here:
importlib 1.0.1 - Backport of importlib.import_module() from Python 2.7
Also check the setup.cfg for celery near the bottom and make sure all the other requirements are met (toward the bottom of the script).

importlib was added to Python in version 3.1, and then backported to Python 2.7. Third party backports are available on PyPI.
Also note that 'backported to 2.7' doesn't imply that all versions after 2.7 will have importlib. Python 3.0, I believe, does not have importlib.
