Looks like you have the wrong redis client version. You should create a virtualenv for CasePro and install everything from pip-freeze.txt, i.e.

virtualenv env
. env/bin/activate
pip install -r pip-freeze.txt

used a venv actually, but used pip-requires not pip-freeze

rowanseymour commented 8 years ago

Ah ok. That will install the latest latest of all dependencies which is not what CasePro is expecting.

citizenrich commented 8 years ago

Ok, yet more fun. Swear I'm following the dev instructions perfectly, except using pip-freeze not requires:

Hmm did you start with a clean virtualenv before installing from pip-freeze.txt?

citizenrich commented 8 years ago

deactivated and rm -rf the env/ dir. Not clean enough?

citizenrich commented 8 years ago

Seems to be working fine on fresh Ubuntu 14.4.3 x64, just may be my Mac.

Only hiccup when using a non-local dev server is that runserver has to be opened up, and getting a strange message. Prob a bad config of mine:

rowanseymour commented 8 years ago

Re the UUID error, seems you've run into this issue where latest CPython breaks kombu https://github.com/celery/kombu/issues/545

I actually fixed this in the refactor branch (just requires updating the kombu version) which I'm hoping to merge later today. If you're just trying to setup a local dev instance, feel free to switch to that branch.

Re the TembaConnectionError. CasePro can't run without a RapidPro instance to connect to. By default it expects to connect to RapidPro on http://localhost:8001/.

Thanks

citizenrich commented 8 years ago

other than setting the api to https://app.rapidpro.io/api/v1, is there any other reason for a temba connection error (beyond blocked ports)?

rowanseymour commented 8 years ago

Not that I can think of. If you switch to the refactor branch you should point the API setting to https://app.rapidpro.io without the api/v1 part as it will use both v1 and v2 API versions.

citizenrich commented 8 years ago

cheers! will check it.
