【问题描述】：
我尝试部署我的 Rails 应用程序（到 Cloud66 和 DigitalOcean），但是在访问该应用程序时，它只是说：
很抱歉，出了点问题。我们已收到有关此问题的通知，我们会尽快进行查看。
根据日志（粘贴在下面），缺少 js_regex gem。但是我无法修复它，因为在本地一切正常。如果我拿走 client_side_navigation gem，一切都可以在生产环境中进行。似乎它无法在生产中加载 js_regex，但我不知道为什么。 （client_side_validations 依赖于 js_regex）
使用 Rails 4.2.2、ruby 2.2.0 和 client_side-validations 4.2.1，js_regex 是 1.0.12 版本。
这里是 nginx 错误日志：
