Hi,
I have a Flask application that uses astropy, and I am trying to deploy it in Apache with mod_wsgi. Here's a minimal example app.wsgi file:
import astropy
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
application = app
It fails to import astropy because it cannot locate the Astropy config files. Here's the traceback from the Apache log file, error.log:
/home/***/***/local/lib/python2.7/site-packages/astropy/config/configuration.py:680: ConfigurationMissingWarning: Configuration defaults will be used due to OSError:Could not find unix home directory to search for astropy config dir

It's running as a user without a home directory. How do I import astropy if I don't have a home directory?
Thanks,
Leo
