Push rejected, failed to compile Multipack app

[sankaet]

So I added

$ heroku config:add BUILDPACK_URL=https://github.com/ddollar/heroku-buildpack-multi.git

$ cat .buildpacks https://github.com/cyberdelia/heroku-geo-buildpack.git https://github.com/heroku/heroku-buildpack-ruby.git

and then I pushed my .buildpacks to heroku

but I am getting the following error, any suggestions?

Does it happens every time you try to deploy?

[sankaet]

yes, should I be using https://github.com/heroku/heroku-buildpack-python.git instead? since this is a django app?

[cyberdelia]

@sankaet Yes, that would help a lot, the ruby buildpack is indicated in the README as an example.

[sankaet]

okay, yes just used

https://github.com/cyberdelia/heroku-geo-buildpack.git https://github.com/heroku/heroku-buildpack-python.git

in my buildpacks and it pushed the update just fine. this is all I need to use geoDjango right?

I followed everything heroku had on this link https://devcenter.heroku.com/articles/postgis

[cyberdelia]

Yes.

Thank you so much @cyberdelia :)
