mysql-Rake上的Ruby on Rails出现问题

我是Rails的新手,所以请原谅我缺乏理解.我已经通过RubyGems安装了最新版本的RubyGems,Ruby,Rails,Rake和MySQL等,但是在开始制作基本的Rails应用程序时遇到了这个问题：

Icarus:temporary atg$rails new people
    ... (output omitted) ...
Icarus:temporary atg$cd people
Icarus:people atg$rake db:create

/Users/atg/.gem/ruby/1.8/gems/rake-0.8.7/bin/rake:31
/usr/bin/rake:19:in `load'
/usr/bin/rake:19

我不知道自己做错了什么,而且我对此很陌生,以至于我一生都在努力工作,我不知道可以调试它吗？有什么想法/指导吗？

感谢所有帮助,并在此先感谢！

解决方法:

如果您是第一次体验,我建议从Rails 2.3.8开始.有许多教程和更广泛的支持. 3.0相当新鲜,但有几个主要变化.无论如何,您最终都可以从2.3.8升级到3.0.0.
