我正在尝试将我的第一个应用程序部署到Heroku.我正在使用SQLite作为数据库.据我所知,Heroku不使用SQLite - 它在后端切换到Postgres.

当我正在部署时,我收到以下错误:

/usr/ruby1.8.7/lib/ruby/gems/1.8/gems/bundler-1.0.0/lib/bundler/runtime.rb:64:in`requirement':没有要加载的文件--sqlite3(LoadError)

我Gemfile(这是我假设导致此问题)如下所示:

source 'http://rubygems.org'

gem 'rails', '3.0.0'        
gem 'sqlite3-ruby', '1.2.5', :require => 'sqlite3'

我究竟做错了什么？

对rails/heroku来说很新.我创建了一个干净的项目来帮助弄清楚heroku在世界上发生了什么.然后我添加一个:

rails generate controller Pages home contact

http:// localhost:3000/pages/home显示了我们的期望.提交,推送到git,推送到heroku.在heroku上打开页面,它返回错误页面:"我们很抱歉,但出了点问题."

heroku日志似乎没有任何有趣的东西,并且异常并没有记录任何不好的事情.

更新:我已将日志缩减为违规位的示例.

这是我正在运行的gemfile

# gemfile
source 'http://rubygems.org'

gem 'rails', '3.1.0'

group :test do
  gem 'sqlite3-ruby', :require => 'sqlite3'
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.1'
end

group :development, do
  gem 'sqlite3-ruby', :require => 'sqlite3'
  gem 'rspec-rails', '2.6.1'
end

我试图以与我一直相同的方式将应用程序推送到Heroku.我正在使用Ruby 1.9.2和Rails 3.2.1.但是,现在我收到此错误消息.我做了它的建议

make sure that `gem install sqlite3 -v '1.3.5'` succeeds before bundling.

注意,即使我在我的gemfile中也这样做了

group :development, :test do
  gem 'sqlite3'
end
group :production do
  gem 'pg'
end

但gem install sqlite3 -v '1.3.5'在终端做,但推动仍然被拒绝.我不知道如何检查它在tmp目录中引用的Gem文件,但即使我这样做,我也不理解它们

有什么建议？

Gem files will remain installed in /tmp/build_1timyd7o5k59l/vendor/bundle/ruby/1.9.1/gems/sqlite3-1.3.5 for inspection.

我按照以下步骤操作:

git clone git://github.com/heroku/ruby-sample.git
cd ruby-sample
heroku create
git push heroku master
heroku open

当我试图运行第4步时,我遇到了以下错误:

$ git push heroku master
