我尝试在我的 MBP 操作系统 10.8.2 上安装Forge 。我已经安装了 Compass、Susy、Sass 和其他 gem,所以我已经习惯了。
但是,安装首先失败,说它需要安装 Rack。所以,我安装了 Rack,它似乎安装成功了。
现在我尝试创建一个 Forge 项目但收到此错误:
[~/Documents/.../ONOTW/onotw_wk] $ forge create onotw
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:230:in `activate': can't activate rack (~> 1.3.5, runtime) for ["forge-0.5.0"], already activated rack-1.4.1 for ["sprockets-2.0.4", "forge-0.5.0"] (Gem::LoadError)

from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1056:in `gem'
from /usr/bin/forge:18
有什么建议么?
