Question

我不确定我何时第一次收到此消息，但错误消息仅出现在我的开发服务器上。生产heroku服务器不会报告任何内容。

不确定为什么要尝试读取assets目录。但是你在dev服务器上没有看到/ assets的原因是rails会以dev模式为/ app / assets / stylesheets提供资源，对于存在的项目，但是因为没有到/ assets的路由（通过{检查） {1}}）您收到错误。

在生产中rake routes在上传到heroku期间执行，因此创建并填充了dir / public / assets。

你可以在你的开发机器上rake assets:precompile看看会发生什么。
