获取java.lang.IllegalArgumentException:没有方法的实现::协议的as-file:#'clojure.java.io /为类找到强制:clojure.lang.PersistentVector当我在MAC上运行lein test或lein repl时OS X.虽然lein repl在eclipse中运行良好(使用逆时针插件)

    :ring {:handler cmp.handler/war-handler

         :init    cmp.handler/init
         :destroy cmp.handler/destroy } …

FileNotFoundException无法在类路径：clojure.lang.RT.load（RT.java:443）上找到ring / util / request__init.class或ring / util / request.clj

当我尝试使用一个我的命名空间时，这在leiningen repl中发生：（使用'cmp.repl）

此问题仅在我的部署环境（Ubuntu Server 12）上发生，但在我的开发环境Mac OS 10.8上运行良好

我想在rails 4.1中使用grouped_options_for_select时预先选择多个选项

方法签名是

grouped_options_for_select(grouped_options, selected_key= = nil, options = {})

selected_key仅允许与精确选项匹配的单个值.我想预先选择多个选项,因为我使用的是多选.反正有没有这样做？
