消除 Rails 2.3 风格的插件和弃用警告
我对 Heroku (keilmiller.herokuapp.com) 上的 rails 3.2.8 应用程序有疑问。
pg，thin并且foreman在我的 gemfile 中用于生产。
我正在使用雪松堆栈。我将我的新应用程序推到了 heroku 上--force。我跑去heroku pg:reset SHARED_DATABASE清除我的旧数据库。Runningheroku run rake db:migrate或任何其他 rake 命令会产生错误。
弃用警告：您在供应商/插件中有 Rails 2.3 风格的插件！
我没有任何 Rails 插件。我知道我过去遇到过这样的问题，但我猜 Heroku 将支持更改为堆栈溢出。我不能再用 Heroku 查看我的旧票了。任何帮助将非常感激。
为什么我的应用程序停止了？
编辑：我刚刚从 heroku 中删除了我的应用程序，并使用 cedar 堆栈创建了另一个应用程序。新的开始。将我的本地应用程序推送到 heroku。尝试查看页面时出现应用程序错误，尝试运行heroku run rake命令时仍然出现插件错误。
编辑：我认为可能与 ruby 版本存在某种不兼容。日志文件有目录from /app/vendor/bundle/ruby/1.9.1但heroku run "ruby -v"产生 1.9.2。我更新了我的 gemfile 以包含 ruby 1.9.3 并推送到 heroku。Heroku 确实像我的本地环境一样运行 1.9.3，但它输出的日志仍然相同。
编辑：我再次清除了数据库，重新启动了 heroku 应用程序，并获得了一个新日志。
编辑：我的载波初始化程序有问题。固定的。推。发布新日志。/app/app/helpers/application_helper.rb:2:in': uninitialized constant FoundationRailsHelper::FlashHelper (NameError) Something is going on I think with this statement in my application helperinclude FoundationRailsHelper::FlashHelper` 使用https://github.com/sgruhier/foundation_rails_helper它在开发模式下完美运行。

回答
由于某种原因，该线程已关闭。我真的不喜欢堆栈溢出。无论如何，“答案”应该是将宝石移出资产组。我不假思索地把它放在那里。解决了这个问题。现在我知道，如果有关于未初始化或丢失的警告，请检查 gem 是否包含在生产中。
