python - Psycopg2 on Amazon Elastic Beanstalk

Question

I'm trying upload my project (in python) that uses Psycopg2 for Amazon Elastic Beanstalk. I'm doing this with a zip file containing my project and an requirements.txt file.

But I'm receiving this error:

Downloading/unpacking psycopg2>=2.4.6 (from -r /opt/python/ondeck/app/requirements.txt (line 3)) Running setup.py egg_info for package psycopg2 Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.
Complete output from command python setup.py egg_info:
running egg_info

How can I solve this on Amazon?

Need postgresql-devel in your container. Create a file '.ebextensions/packages.config' with the contents:

packages:
  yum:
    postgresql94-devel: []

Replace 94 in postgresql94-devel with whatever version of postgres you need. For example, postgresql93-devel for postgres 9.3.
