Clojure 我对core.cache有什么错？

然后我进入并像这样编辑project.clj文件

lein new caching

我执行：

(defproject caching "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.3.0"]
                 [org.clojure/core.cache "0.5.0"]]
  :plugins [[lein-swank "1.4.3"]])

依赖关系被拉出来，一切都很好

然后，受以下示例文档的启发，我编辑core.clj

并在编译core.clj时返回以下错误。所以我做错了什么？有人能让它正常工作吗

(ns caching.core
  (:require [clojure.core.cache :as cache]))

(cache/lru-cache-factory {} :limit 2)

---

对于core.cache的版本0.5.0，

lru缓存工厂

似乎有不同的args列表

这是一份来自commit的diff的副本

---

请尝试使用core.cache的0.6.0-SNAPSHOT，以便按照教程进行操作。

如果要继续使用0.5.0，可以将代码更改为如下所示：

-  [limit base]
+  [base & {limit :limit :or {limit 32}}]

和我做的差不多。我很简单。
