Ruby on rails &引用；config.cache_classes=true"；没有要加载的此类文件--/path到app/app/config/environment（LoadError）

当config.cache\u classes设置为true时，应用程序不会在生产模式下启动。它给出了stacktrace的以下错误：

我正在使用以下宝石：

我真的很感谢任何帮助

我知道，我在做一些愚蠢的事情（虽然不全是我，还是老设计师的故事。我应该检查git提交）。我在app目录和project目录中都有spec文件夹。但我还是不明白为什么它能用

config.cache_classes = false

---

在production.rb.

中，如果您尝试“rails s-e生产”，您会得到什么结果？我得到了相同的结果，问题无论如何都会得到解决。你还是可以帮忙的。看看我的答案。

config.cache_classes = false
