Rails 3.2，Heroku 弃用警告 - “弃用警告：你有 Rails 2.3 风格的插件” [重复]

Question

可能重复：
Rails 2.3-style plugins and deprecation warnings running task in Heroku

几天前，我决定将我的 Rails 3.1 应用程序升级到 Rails 3.2。在生产和开发环境中，一切都在我的本地机器上运行良好。当我将应用程序推送到 Heroku 时，出现错误并且应用程序崩溃。

错误信息：

我向 Heroku 支持部门发送了电子邮件，回复是

你好-

最后一行指出了 Fog 的问题 - 一个用于与 Amazon 等云提供商通信的库。

您会确保“雾”gem 已添加到您的应用中吗？

我 100% 确定 gem 在那里，因为您可以看到我的 gem 文件。然后再次回复

您能否在“生产”模式下在本地重现此问题？

如果将“瘦”gem 添加到 Gemfile，则可以使用“bundle exec thin start -e production”模拟 Heroku 环境

我已经这样做了，一切都在我的本地机器上运行。我对解决方案有点迷茫。我读了这个Rails 2.3-style plugins and deprecation warnings running task in Heroku，我不鼓励尝试这种黑客作为解决方案。作为另一个解决方案，我决定将我的应用程序降级到 Rails 3.1，但问题仍然存在。我在这里错过了什么？

我怀疑这来自我与上传器一起删除的 Carrierwave gem。但是 Heroku 仍然提到它。我的配置文件中没有关于载波的任何内容。

Answer 1

据我所知，该错误与插件或 Rails 3.2 无关，它们已被弃用。在我看来，您已错误地卸载了carrierwave。

错误消息指出您仍然有一个 config/initializers/carrier_wave.rb 并且它仍在尝试引用丢失的 CarrierWave 对象。

我建议确保正确删除您的载波，并从 git 中删除。
