python - ImportError: No module named config on Travis-CI build -


i'm having import error on travis builds, error related configuration of flask:

from flask import flask  app = flask(__name__) app.config.from_object('config')

on local machine, flask app run correctly. on travis here error trace

what's wrong configuration?

import_string takes absolute module imports. since config not top-level module, part of webapp, need specify webapp.config. see http://flask.pocoo.org/docs/0.10/config/#configuring-from-files:

app = flask(__name__) app.config.from_object('yourapplication.default_settings') app.config.from_envvar('yourapplication_settings')
