我将 Heroku 环境设置为暂存，但我的资产始终在生产环境中编译。
Here's heroku config:
GEM_PATH => vendor/bundle/ruby/1.9.1
LANG => en_US.UTF-8
PATH => bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin
RACK_ENV => staging
我已经添加了一个例外production.rb文件，这样我就知道编译资产时正在运行哪个环境。服务器启动运行良好heroku run console显示我正在运行分期。
就是跑步的时候assets:precompile它始终处于生产状态。
如果需要，我很乐意发布任何其他配置文件。
我可以补充一点，我正在 Heroku 上运行 Rails 3.2.2 和 Cedar 堆栈
输出来自heroku run rake about:

和跑步heroku run rake assets:precompile gives:
/usr/local/bin/ruby /app/vendor/bundle/ruby/1.9.1/bin/rake assets:precompile:all RAILS_ENV=staging RAILS_GROUPS=assets
我应该放弃并给 Heroku 发送电子邮件吗？
