Clojure,全新安装:无法解析符号:some->

我刚安装了最新版本的Clojure,在遵循Liberator教程(http://clojure-liberator.github.io/liberator/tutorial/getting-started.html)的同时,我得到以下异常:

Exception in thread "main" java.lang.RuntimeException: Unable to resolve symbol: some-> in this context, compiling:(clout/core.clj:88)

我在Ubuntu 15.04上.Leiningen verison 2.5.3.Java版本1.7.0_91.

Lein Repl工作正常,虽然它理解(some ...),它无法解决(some-> ...)

我一直在寻找几个小时,它看起来some->应该是Clojure v1.5 +的标准功能

我为什么不拥有它？

从教程链接中,project.clj是:

(defproject liberator-tutorial "0.1.0-SNAPSHOT"
  :plugins [[lein-ring "0.8.11"]]
  :ring {:handler liberator-tutorial.core/handler}
  :dependencies [[org.clojure/clojure "1.4.0"] ;; <-!!!!!!!!!!!!!!!!
                 [liberator "0.13"]
                 [compojure "1.3.4"]
                 [ring/ring-core "1.2.1"]])

所以你正在运行Clojure 1.4.0.尝试将其更改为1.7.0左右.
