目前，我已经在我的 Ubuntu 11.10 上安装了 Ruby（ruby 1.9.3p194（2012-04-20 修订版 35410））。想要使用“sudo gem install amqp”安装 AMQP gem。但它失败并显示以下错误消息：

    Building native extensions.  This could take a while...
    ERROR:  Error installing amqp:

如果有人可以帮助我，将不胜感激。谢谢。

为了编译本机扩展，您需要一个编译器。只需使用以下命令安装 g++ 和朋友：

sudo apt-get install build-essential

然后再试一次。
