我在将已从4.x更新到5.1的Rails应用程序移动到生产中时遇到问题。在开发中工作正常，但是当我使用Capistrano移动到生产环境时，我得到了以下内容。请注意，类似问题的每个帖子在他们的代码中似乎都有语法错误，虽然它可能（相当;）我也这样做，但我没有看到MY js代码下面的引用，只有“库”代码。除非3528：621是我的代码的连接文件？无论如何，我预编译开发中的资产，似乎工作正常。有关如何发现这一点的任何建议？
几分钟后更新：当我在DEV中进行编译时出现同样的问题！抱歉。现在，找出这是什么线路最简单的方法是什么？

最后我只是通过我的所有javascript，禁用一半，然后另一半，然后当我到达文件时，做了同样的事情。花了一段时间，但我找到了违规行，将其删除，一切正常。 （好吧，那个问题;）
德里克 - 感谢您的支持，但我发现了问题。祝你有美好的一天
