Rails栏杆gem错误“未定义方法：’少’”
我刚刚用gem update和bundle update更新了我的rails app的gem。 当我尝试用rails s测试它时，它给了我这个错误：
/Users/Richard/.rvm/gems/ruby-1.9.2-p318/gems/railties-3.2.3/lib/rails/railtie/configuration.rb:85:in method_missing’：undefined method /Users/Richard/.rvm/gems/ruby-1.9.2-p318/gems/railties-3.2.3/lib/rails/railtie/configuration.rb:85:in less' for # (NoMethodError)
其余的错误消息如下：

这是Twitter Bootstrapgem的错误吗？ 我还在学习，如何解决这个问题呢？ 任何帮助都很棒。
twitter bootstrap gem取决于较少的gem。 来自文档 ：
gem "therubyracer" gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS gem "twitter-bootstrap-rails"
我个人发现twitter bootstrap更容易将文件从官方网站转储到vendor / assets目录中。 从gem中更新比手工更容易，但是当更新bootstrap时，你有点想“手工”并且“通过眼睛”检查它 – 我更喜欢额外的努力，以确保它不会得到做得很轻松。 此外，很难从gem中删除某些（例如）响应部分，没有（据我所知）“未指定”样式。 响应式内容在大小方面从版本变为版本，因此您不能仅仅依赖它完成所有工作。 我真的看不到使用gem的任何优势。
更新
现在有一个官方的gem，我建议检查： https ： //github.com/twbs/bootstrap-sass
