Question

当我尝试访问我的rails服务器时出现以下问题：

无法启动Web应用程序。 Phusion Passenger列出了以下更多信息。

任何想法？

原因

查看堆栈跟踪和错误消息，我怀疑你指定了：

app.config.assets.precompile = false

在config/environments/production.rb中。 但这不是它的工作原理。

你正在使用的宝石，bootstrap-saas appends the array应该在那里：

app.config.assets.precompile << %r(bootstrap/glyphicons-halflings-regular\.(?:eot|svg|ttf|woff)$)

如果你怀疑precompile=false，那就解释了你为什么会这样做：

undefined method `<<' for false:FalseClass (NoMethodError)

解决方案

有关如何在production.rb中配置app.config.assets.precompile的详细信息，请参阅Asset Pipeline Rails Guide
