rails 3.2.0 and heroku

Question

I have some troubles with rails 3.2.0 & ruby 1.9.3, I only created a new app with rails new command and I'm trying to deploy to heroku. I'm having the following app error:

An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.

After run heroku logs I get the following error:

Could not find activemodel-3.2.0 in any of the sources

Thanks in advance!!!!

can you paste all references to activemodel from Gemfile.lock please? — stephenmurdoch, Jan 21 '12 at 18:03
ps - [forem](https://github.com/radar/forem.heroku.com) runs on 3.2 on heroku so I'm guessing this can be done — stephenmurdoch, Jan 21 '12 at 18:04
added Gemfile.lock, Im trying for downgrade rails but rails executable stills reference to 3.2 and cant run rails:(, Thanks!!! — nachoesmite, Jan 21 '12 at 18:17
I downgrading ok, the prob was i were on old app directory:P Thanks! — nachoesmite, Jan 21 '12 at 19:24
Here's a detailed tutorial that shows how to set up Ruby 1.9.3 on Heroku: [Using Rails 3.2 and Ruby 1.9.3 on Heroku](http://railsapps.github.com/rails-heroku-tutorial.html) It covers deploying an app to Heroku in depth. — Daniel Kehoe, Jan 26 '12 at 19:18

Rails 3.2 applications run fine on Cedar, I've just upgraded several applications to run on Cedar and are running on Heroku. Once you've updated your Gemfile and Gemfile.lock make sure you commit them both and push them both to Heroku. Heroku will then rebundle your application to use Rails 3.2.

Incidentally, I don't specify any version numbers on sass-rails or uglifier in my Gemfiles.

Of course, you can test in production mode running locally before you push to Heroku to see if it's going to work.

Had a similar problem today. After creating and pushing a new app, heroku said "Could not find multi_json-1.3.1 in any of the sources"

This is how I solved it:

Delete local Gemfile.lock
Run bundle install
Push again => Everything works well

For what it's worth, I had this same problem not on Heroku, but on one of our local deployment servers. We were running on a server with Ruby 1.8.7-p72. RubyGems was shamefully out of date — it had v1.3.7 on it. Running a gem update --system to bump it up to v1.8.15, and then redeploying, worked like a charm (despite all the invalid gemspec warnings we received in the log).

Not specific to Heroku, but hopefully helpful to any Googlers that come wandering in here like I did.

Thanks found a bunch of Heroku references but nothing on managed servers. Your solution solved my problem. – Cimm Jan 26 '12 at 16:32
Thanks! [This perl one-liner](http://stackoverflow.com/a/8181215/194869) fixed all the gemspec errors in a pinch, too. Painless! – Ben Kreeger Jan 26 '12 at 18:07

Check the stack by using heroku stack. Your app might not be on 'cedar' stack. I had the same issue and re-creating the app on 'cedar' resolved the issue.

I used latest Rails from "3-2-stable" and the problem has also gone.

Heroku only supports up to Rails 3.1 (cedar stack).

I'm trying to downgrade from 3.2 to 3.1,and I get "Could not find railties-3.2.0 in any of the sources", can anyone helps me on that! Thanks a lot!!! – nachoesmite Jan 21 '12 at 18:11
To downgrade, make sure you run `bundle install` after you change the versions back to their original `3.1.x` versions. – Behrang Jan 22 '12 at 04:39

Simply not true - Heroku is not bound to any particular version of Rails – Neil Middleton Jan 23 '12 at 17:02
@Neil-Middleton Only cedar stack supports the asset pipeline (http://devcenter.heroku.com/articles/rails31_heroku_cedar) so in that sense, it does matter which stack you use. I haven't found anywhere that cedar stack officially supports 3.2. – Greggory Rothmeier Feb 01 '12 at 21:22
Cedar doesn't officially support anything as it's not yet GA. I have numerous apps running 3.2 on Cedar right now. – Neil Middleton Feb 02 '12 at 12:47
