Leiningen是一个Clojure项目管理工具。

安装过程如下:

1. 下载lein脚本

https://raw.github.com/technomancy/leiningen/preview/bin/lein

2. 复制到/usr/bin目录下,并允许执行

 

mv lein /usr/bin/
root@chenshu-yangzhou-home:~/Downloads# chmod +x /usr/bin/lein 

3. 运行lein命令,不要使用root权限

注意国内可能需要使用proxy才能下载,参考我的关于终端如何设置http代理的方式。

如果因为网络原因安装失败,删除掉~/.lein目录后重新执行lein命令即可。

现在可以启动一个REPL会话,上一片里面用的是java -cp 命令,这里更简单:

 

$ lein repl
nREPL server started on port 55538
REPL-y 0.1.0-beta10
Clojure 1.4.0
    Exit: Control+D or (exit) or (quit)
Commands: (user/help)
    Docs: (doc function-name-here)
          (find-doc "part-of-name-here")
  Source: (source function-name-here)
          (user/sourcery function-name-here)
 Javadoc: (javadoc java-object-or-class-here)
Examples from clojuredocs.org: [clojuredocs or cdoc]
          (user/clojuredocs name-here)
          (user/clojuredocs "ns-here" "name-here")
user=>
输入一个lisp表达式看看:

 

 

 

user=> (+ 1 2)
3
能够运行。注意=>左边的user代表当前的namespace.
