I'm trying to deploy a Rails 3.1 application for the first time on Heroku. I set it to the Cedar stack, removed the sqlite3 gem but when I push the code to Heroku I get this error:
-----> Installing dependencies using Bundler version 1.1.rc Running: bundle install --without development:test --path vendor/bundle --deployment Fetching gem metadata from http://rubygems.org/....... (...)
Installing rails (3.1.0) Installing sqlite3 (1.3.4) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks! /usr/local/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError) /usr/local/bin/ruby extconf.rb checking for sqlite3.h... no
I've no idea why bundle install is trying to install sqlite3. Take a look at my Gemfile and Gemfile.lock:
Gemfile
source 'http://rubygems.org'
gem 'rails', '3.1.0'
gem 'json'
gem 'pg'
gem 'thin'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
# gem 'sass-rails', " ~> 3.1.0"
# gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
gem 'jquery-rails'

How can I fix it?
When I ran into the problem, turns out I'd forgotten to commit my changes after bundle install
. Doh! git status
should indicate unstaged changes for the gem files.
I has the same problem and zoltarSpeaks' solution fixed it for me. I had the taps gem installed after reading this article that indicated it would be necessary for pushing from a local sqlite3 to production postgresql: http://batsov.com/articles/2011/10/30/deploying-rails31-apps-on-celadon-cedar/. Turned out I didn't need the taps gem after all, but it was clearly the problem. Removed the reference, bundle update, all systems go.
try deleting Gemfile.lock and run Bundle Install, commit and push
