Rake 中止，没有要加载的文件 -- paperclip

Question

我正在尝试将 Rails3 应用程序部署到 Heroku，但是当我 rake db:create 或 rake db:migrate 到 heroku 时，出现“Rake aborted”错误。

db:push 确实发送了架构、索引和数据，但我在 app.heroku url 处收到“应用程序错误”。

我尝试删除并创建一个新的 Heroku 应用程序，但遇到了同样的问题。

回形针似乎是原因。我检查过回形针在 gemfile 中。我已经更新了所有宝石。我尝试从 gemfile 中删除明显的依赖项。但我仍然收到“耙子中止”错误。

如果有任何想法或有用信息的提示，以帮助我了解发生了什么以及如何解决它，我将不胜感激。

这是heroku db:create --trace

heroku 日志文件很长，唯一看起来相关的是

在我本地的Postgres 开发环境中一切都工作正常。

如果我错过了任何重要信息，请告诉我。

我感谢任何有助于理解调试此类问题的最佳方法的指示。我不知道从哪里开始！

谢谢

Answer 1

经过大量搜索，答案就在 application.rb 文件中。我有一行“需要回形针”，我删除了它，一切正常。
