Difficulty with dev setup for Ubuntu 16.04

[nshiff]

seigenblues mentioned on reddit that the project was interested in some frontend work. I don't see any to-dos for frontend, so I figured I would clone the project and just see the state of things. I'm attempting to follow along with the readme instructions, but here's where I am.

1. Install Python3 - ok

2. Install pip - ok

3. Install postgres - this seemed to work. On my version Ubuntu 16.04, there is the package postgresql and postgresql-9.5. In order to get 9.4, I used the linked instructions to use an alternate repository. This seemed to work.

4. Install the python dependencies with pip. - This does not appear to be working. Here's what I have.

~/src/online-ratings/web$ pip install -r requirements.txt

Failed to build psycopg2

I found a few references on Stack Overflow with failures to build this package, but none of the suggestions worked for me (installed autotools, ran pip with sudo).

5. Run the tests! - ok

Linux: Install docker and docker-compose - ran hello-world with success

$ cp .env_example .env
$ docker-compose build
WARNING: Please be aware that .yml is the expected extension in most cases, and using .yaml can cause compatibility issues in future.

ERROR: In file './docker-compose.yaml' service 'version' doesn't have any configuration options. All top level keys in your docker-compose.yml must map to a dictionary of configuration options.

So I commented out the "version" line, but then fail with:

WARNING: The DB_NAME variable is not set. Defaulting to a blank string.
WARNING: The DB_USER variable is not set. Defaulting to a blank string.
ERROR: Validation failed in file './docker-compose.yaml', reason(s):
Unsupported config option for 'volumes' service: 'pgdata'
Unsupported config option for 'services' service: 'psql'

I don't understand... I modified .env with the values for an empty database I set up in Postgres. Any tips appreciated.

Can you run docker --version?

They changed the docker-compose.yml file format in 1.8 I think, to accept a new version: '2' config, so if you have a really old version for some reason, it won't understand the new version.
