郑重声明：俺是菜鸟，学习rails纯粹是兴趣，如有雷同纯属巧合。
但是对俺打击也太大了，连续在几种linux环境下安装都不成功。
两个星期了，找了n多个论坛，第一次rails demo 执行完毕后，以下是提示：

还是没有人理我，好几天了，还是解决不了问题，肯定哪里一个很简单的地方没有搞懂。

唉貌似我连rails 都没装成。。非常郁闷在学习RUBY中

1. Rails的框架是基于Ruby语言的，就像Struts框架是基于Java一样，所以先去下载Ruby安装包，http://rubyinstaller.rubyforge.org。也可以在ubuntu中用打开终端输入命令:

代码：全选

sudo apt-get install ruby

接着安装Rails:

代码：全选

sudo apt-get install rails

代码：全选

sudo apt-get install libapache2-mod-ruby libapache2-mod-fcgid libfcgi-ruby1.8 libmocha-ruby1.8

代码：全选

sudo apt-get install mongrel

代码：全选

 mkdir /home/hbs/work

代码：全选

cd /home/hbs/work

代码：全选

rails demo

代码：全选

 cd demo/script

代码：全选

./server webrick

2.访问web页面

如上图图中的第三行告诉我们rails的web服务端口号是3000，访问地址为http://127.0.0.1:3000

如果访问成功会得到如下画面：

rails 要使用官方的, 不要用ubuntu源里面的.

另外, 不要随便使用sudo.
sudo rails depot 这句话是明显错误的. 在自己目录里面不要使用sudo.

[问题]郁闷呀，使用rails出现下面提示，貌似大伙都比较顺利没有出现俺类似的错误。
