我是Ruby开发的初学者,所以道歉这是一个面子问题。
在mac OSX上我安装了ruby 1.9.3,然后通过命令'gem install selenium-webdriver'安装了一个gem,然后我安装了eclipse作为IDE。
然后我写了一个简单的类,需要'selenium-webdriver'宝石。
class Cheese
require 'rubygems'
require 'selenium-webdriver'
... rest of code class.
我可以使用irb或ruby(即ruby ./path to file / cheese.rb)从命令行运行cheese.rb,但是当通过eclipse GUI运行脚本时,我收到错误:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- selenium-webdriver (LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require'
from /Users/bryan/Documents/workspace/New Se Project/Cheese.rb:3
这表明Eclipse存在配置问题。请注意,安装的默认ruby版本是来自rvm-list的1.9.3,但Eclipse仍然“绑定”到1.8。谷歌搜索表明这可能是一个路径问题,但我不熟悉Mac OSx上的环境变量。
* 如何重新配置Eclipse(或Aptana)以“看到”已安装的宝石? *

我遇到了同样的问题。我首先尝试了本教程:http://net.tutsplus.com/tutorials/ruby/how-to-install-ruby-on-a-mac/
这没有帮助。
然后我在超级用户中看到了这个条目:https://superuser.com/questions/154292/ruby-rubygems-why-do-i-always-get-error-messages-when-trying-to-install-gems并使用sudo运行gem install帮助了我。
