我在Heroku上运行我的应用程序时遇到了一些困难 - 该应用程序在我的本地计算机上运行完美。 :( 日志报告了我的ActiveSupport gem的一些问题。所以，我采取了这些措施：
1）重新安装ActiveSupport gem
2）将我的Git提交回到前一个工作正常的Git。
3）将我的应用程序复制到一个新文件夹 - 创建一个新的Git Repo，在新文件夹中做bundle install，制作提交，添加Heroku远程源，将应用程序推送到Heroku - 没有帮助。
My Rails版本：3.0.3 Ruby：1.8.7
这是我的Heroku日志（更新）
令人惊讶的是，我在./bundle/gems/ruby/1.9.1之后获得了1.9.1，而该项目使用的是Ruby 1.8.7。我有什么想法可以解决这个问题吗？

如果你使用Rails 3x，你应该使用rubygems 1.9.2，而不是1.8.7。还要确保在environment.rb中声明了正确的rails版本，如果你在rails 2x以及你的Gemfile上。
所以对于rails 2x项目
的environment.rb
RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION
的Gemfile
gem 'rails', '2.3.8'
和rails 3x项目
的Gemfile
gem 'rails', '3.0.7'
这样heroku知道在哪个gem设置下加载哪个rails版本。你应该能够
git push heroku master
如果全部理顺

我的app/helpers目录中有一个名为errors_helper.rb的文件，不幸名为errors_helper.rb.rb
更改名称扩展名解决了我的问题！
