Put postgres in your Gemfile . As far as I remember the Jeromy FAQ points to this issue.

Hi!

Look at mine Gemfile. Perhapse you find some idea how to set "pg" gem.

As far as I understand the working of heroku deploy, it does not look at your Gemfile, but at your Gemfile.lock, so if you "bundle install --without production" (or what ever the command was), pg will not be in your Gemfile.lock, so heroku does not see it! Same point is for your rubyracer-gem... So you should make them visible even for your dev-env.

Its possible that I am wrong, but even then I would prefer to use postgres in development, so stumble over problems with pg already locally and dont have to debug with remote when there are any problems in the pg-implemention.

I’m also having an same error with http://smoothipod.heroku.com/ while following with http://ruby.railstutorial.org/chapters/beginning#top by Michael Hartl. Also another similar (little different) error with http://meinkampf.heroku.com/.

The strange thing is, both of these applications work on my http://localhost:3000 but not on heroku. I am stuck in this since yesterday and haven’t found any solutions yet. Any help would be really great. Thanks in advance. :slight_smile:

I also ran into the same error after following the instructions when following the instructions in Ruby on Rails Tutorial: Learn Rails by Example http://ruby.railstutorial.org/chapters/beginning#top by Michael Hartl.

The problem is that Heroku doesn't support the SQLite.

The solution is to convert your database to either MongoDB or PostgreSQL. The instructions can be found at http://railsapps.github.com/rails-heroku-tutorial.html.

Thank you, that worked. :slight_smile:
