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.

mauto/Gemfile at master · otobrglez/mauto · GitHub

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 H… 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.

Thank you, that worked.

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 H…

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.
