我正在尝试安装rails 3.0.3,每次都会出现以下错误:
Insecure world writable dir /usr/local in PATH, mode 040777
当我检查它是否安装时,我收到此错误:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:827:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:261:in `activate'
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:68:in `gem'
from /usr/bin/rails:18
知道我做错了什么吗？对不起,我是个新手!
