Question

我对ruby和dashing完全陌生，只是在我的机器上安装了它们。

当运行划线开始时，会引发一个神秘的错误。

`require'：无法加载此类文件 - 2.0 / ruby_http_parser（LoadError）

任何想法是什么，或如何解决这个问题？

谢谢！

Answer 1

将您的Gemfile编辑为：

gem 'em-websocket', github: 'igrigorik/em-websocket'

Ruby依赖地狱。最有可能与Ruby 1.8,1.9共存。在我的ubuntu 13.10机器上一切正常，但在一个centos 6.5 ruby 1.8默认情况下没有添加1.9。

对于任何有兴趣的人，

我重新安装了版本，使用版本1.3.2而不是1.3.1，重新创建了sweet_dashboard_project，捆绑并启动它，现在它正在工作。
