我從download site下載clojure 1.2和clojure-contrib-1.2.0.jar。導入clojure.contrib.generic.math-functions
我找到了關於math functions的信息。
正如示例中所示,我試圖運行代碼。
(ns your-namespace
(:require clojure.contrib.generic.math-functions))
(println (abs 10))
但是,我得到以下錯誤,當我運行如下。
CLOJURE_JAR=/Users/smcho/bin/jar/clojure.jar:/Users/smcho/bin/jar/clojure-contrib-1.2.0.jar
java -cp $CLOJURE_JAR:$CLASSPATH clojure.main SOURCE.CLJ
Exception in thread "main" java.lang.Exception: Unable to resolve symbol: abs in this context (hello.clj:4) at clojure.lang.Compiler.analyze(Compiler.java:5205) ... at clojure.main.main(main.java:37) Caused by: java.lang.Exception: Unable to resolve symbol: abs in this context at clojure.lang.Compiler.resolveIn(Compiler.java:5677) at clojure.lang.Compiler.resolve(Compiler.java:5621) at clojure.lang.Compiler.analyzeSymbol(Compiler.java:5584) at clojure.lang.Compiler.analyze(Compiler.java:5172) ... 25 more
可能是什麼問題?
根據您確切的需要,clojure.contrib.math可能更可取。 – 2010-08-20 03:03:14
