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，我遇到错误：
$ git push heroku master

您的问题出在sqlite3 gem：
An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue.
您必须将pg gem添加到Gemfile组中的production，因为Heroku使用PostgreSQL。
您可以继续在sqlite3和development群组中使用test。
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end

1）首先，您必须在您的操作系统和所有库sqlite3上安装sqlite-devel
2）然后在Gemfile中
group :production do
gem 'pg'
end
group :development, :test do
gem 'sqlite3'
end
3）bundle install
4）git add ..
5）git commit -m "..."
6）git push heroku master
