Error installing nfldb Python module

[keithfabean]

When I tried to install the Python module I'm getting the below error. I've searched my machine and do not have a pg_config file anywhere. I'm using the Postgres DB Mac app (Postgres v9.5.3.0) the closest thing I've found is a postgresql.conf file in the Postgres data directory.

(complete results from the install command) pip2 install --no-cache-dir nfldb

Not sure but, Try adding the path to your config file to "def config" in db.py . For example to add 'C:\Python27\share\nfldb\config.ini')

def config(config_path=''): paths = [ config_path, path.join(sys.prefix, 'share', 'nfldb', 'config.ini'), path.join(_config_home, 'nfldb', 'config.ini'), 'C:\Python27\share\nfldb\config.ini' ]

Hmmmmm. I don’t find a file named db.py or a nfldb config.ini anywhere on my machine. I’m running a Mac. My Python (2.7) install doesn’t have anything like the folder structure you have in the example. My python path looks more like this: /Library/Python/2.7/site-packages/pip-8.1.2-py2.7.egg/EGG-INFO

I was already running the Postgres app so I didn’t follow the Russ Brooks postgres install steps referenced in the install guide. I ran the DB scripts for NFLDB to import the data into an existing DB/Schema for the app I’m building.

Eventually I want to be able to use the Python module in a Heroku environment to update nfldb tables on a Heroku/Postgres instance. Or am I barking up the wrong tree here and need to find a different source for the NFL game data?

@keithfabean @D3Design's suggestion is unfortunately off the mark. (You don't have the directory structure that @D3Design showed because you haven't successfully installed nfldb.) The error message you're seeing is a result of not having the appropriate PostgreSQL libraries installed. Namely, just because you have PostgreSQL the app installed doesn't mean you have the necessary libraries to write programs against it. Unfortunately, I'm not a mac user so I don't know what the proper path is for getting the necessary libraries. On Linux distros, this is usually the part where you install something like postgresql-dev or libpq-dev or similar.

You're not barking up the wrong tree. nfldb is a bog-standard Python module that makes bog-standard use of PostgreSQL. Unfortunately, bog-standard use of PostgreSQL in Python-land means using a C library, and using a C library means you need to figure out how such things are installed on your platform.
