这个问题，搞了我一个下午，都耽误了跟老婆吃饭的时间。最后借助stackoverflow解决掉了。
http://stackoverflow.com/questions/10455527/sqlite3-h-missing-when-pushing-rails-app-to-heroku
说一下，解决方案吧：
1、找到项目的gemfile文件，打开之后，修改gem sqlite3为：
gem 'sqlite3', :group => [:development, :test]
group :production do
gem 'thin'
gem 'pg'
end
2、删除掉gemfile.lock文件
3、运行 `bundle install --without production
4、运行git add .
5、运行git commit -m "bundle updating sqlite3"
6、运行git push heroku master
OK，完美解决了。。原因，我也不知道，我就是个彩笔
