新安装的Ruby gems未显示在$LOAD\u路径中

我使用MacPorts来管理我的Ruby/Rails/Gems安装。最近在执行

gem安装wirble

之后，当我启动irb实例时，wirble无法加载。以下是输出：

$ irb --simple-prompt
Couldn't load Wirble: no such file to load -- wirble

Wirble gem未显示在我的$LOAD\u路径中：

gem肯定安装了：

$ gem list |grep -i wirble
wirble (0.1.3)

它位于

/opt/local/lib/ruby/gems/1.9.1/gems/wirble-0.1.3/

如何将我安装的这个和未来的gems附加到我的$LOAD\u路径中？

您是否需要irb中的RubyGems

require 'rubygems'

在需要任何宝石之前可能是必要的。您还可以将此行放入

~/.irbrc

中，以便在irb启动时自动需要您的RubyGems

我不确定为什么您的一些gem会出现在加载路径中--gem通常不会出现在

$：

中，这是我做的

使用了这个版本：它成功了

希望有帮助

我使用的是Ruby 1.9.1，应该指定它。Ruby1.9不需要使用require'rubygems'
