加载clojure-contrib [英] loading clojure-contrib

问题描述

我是新的整个JVM的东西，并试图玩clojure。我试图加载clojure-contrib和失败：

I'm new to the whole JVM thing, and trying to play with clojure. I'm attempting to load clojure-contrib and failing:

# in bash
$ java -cp /path/to/clojure.jar:/path/to/contrib.jar clojure.main

# in REPL
user=> (require 'clojure.contrib.math)
nil
user=> (sqrt 2)
java.lang.Exception: Unable to resolve symbol: sqrt in this context (NO_SOURCE_FILE:10)

任何指针都会很棒 - 谢谢。

Any pointers will be great - thanks.

推荐答案

我不是专家，命名空间问题。我使用的解决方案是：

I'm no expert, but it seemed like a namespace issue. The solution I employed was this:

;; for REPL
user=> (ns user (:use clojure.contrib.math))
nil
user=> (sqrt 2)
