solvable
In requirements.txt, changed gunicorn==19.0.0to gunicorn==18.0.0, and he did the trick. Version 19.0.0 is interrupted with Python 2.x, and this prevents the installation of psycopg2.
Original question
I have the following in requirements.txt:
Django==1.6.5
South==0.8.4
argparse==1.2.1
dj-database-url==0.3.0
dj-static==0.0.5
django-toolbelt==0.0.1
gunicorn==19.0.0
psycopg2==2.5.2
pystache==0.5.4
static==1.0.2
wsgiref==0.1.2
However, when I click on Heroku, it does not install psycopg2or even mention giving up this dependency.

When I try to syncdatabase, of course, he complains that it is psycopg2not installed.
How can I get Heroku to install a missing dependency? . I will be very grateful for the constructive idea.
My database setup if this is interesting for this problem:
DATABASES = {}
if ENV_TYPE == 'development':
DATABASES['default'] = {'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),}
else:
DATABASES['default'] = dj_database_url.config()
Update
SyntaxError, gunicorn. , psycopg2? , .
