大佬教程收集整理的这篇文章主要介绍了ruby-on-rails – 如何在ubuntu 12.04上启动rails server localhost：3000，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我是铁轨上的ruby的初学者.

我在官方网页上做了一切. (http://rubyonrails.org/download)

我尝试启动新项目,但localhost doest无法在ubuntu 12.04上运行.

我使用这些命令：

rails new /home/mehmet/Desktop/test/

这是控制台输出：

你有什么主意吗？我如何创建一个新项目以及如何看到localhost：3000？

编辑：

我想,我的问题是关于服务器.

我使用Rails s命令启动服务器,它需要一些错误：

    from script/rails:6:in `<main>'

解决方法

cd /home/mehmet/Desktop/test/

bundle install

rails s
