我通过 lynda.com 开始了有关 RoR 的初学者教程.我按照信中的说明进行操作.到目前为止一切正常，直到我开始访问 Webrick.当我输入rails server"开始工作时，我收到以下错误消息.

I started a beginner's tutorial on RoR through lynda.com. I followed the instructions to the letter. Everything was working so far until I got to accessing Webrick. When I typed in "rails server" to begin work, I got this error message below.

我正在使用

• iMac
• 红宝石 1.87
• 宝石 1.7.2

由于我对 Ruby 没有任何经验，所以我不知道如何解决这个问题.

Since I'm not experienced with anything Ruby, I'm lost on how to fix this.

提前感谢您的关注和可能的帮助.

Thanks in advance for your attention and help if possible.

推荐答案

在终端运行这些:

gem install bundler
bundle

然后你应该可以启动服务器了.

And then you should be able to boot the server.

编辑:您真的应该考虑使用 rvm 来管理您的 ruby​​ 安装和宝石.安装它们也会为您节省大量时间和精力.

Edit: You should really look into using rvm to manage your ruby installs and gemsets. It'll save you a lot of time and effort in installing them too.
