How can I install packages on my heroku app?

Question

I have an app that makes use of shortuuid (https://pypi.python.org/pypi/shortuuid/0.1) that is working fine locally when I run it with runapp.py:

import os

         


        

Answer 1

I usually create a requirements.txt file that contains the packages:

Flask==0.9
Jinja2==2.6
Werkzeug==0.8.3
distribute==0.6.27
wsgiref==0.1.2

Flask-Cache==0.10.0

gunicorn==0.17.2

You can create that file with pip:

$ pip freeze > requirements.txt

Answer 2

Place a requirements.txt in the root directory of your git repo, with your required dependencies (specified in pip/easy-install format).

Example taken from the Heroku website:

Flask==0.8
Jinja2==2.6
Werkzeug==0.8.3
certifi==0.0.8
chardet==1.0.1
distribute==0.6.24
gunicorn==0.14.2
requests==0.11.1
