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 replnREPL server started on port 55538REPL-y 0.1.0-beta10Clojure 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.

<p>1 安装maven，maven是java开发常用的项目构建工具，提供jar包的管理功能，因为leiningen需要使用maven的软件仓库进行包的管理，因此，我们先要安装maven。从官方下载压缩包 <br />下载网站：<a href="http://maven.apache.org/download.html">http://maven.apache.org/download.html</a> <br />下载完毕，解压到本地目录，我放置在G:\server\apache-maven-3.0.5 <br />添加环境变量：各位同学请输入自己的路径 <br />M2_HOME =&gt; G:\server\apache-maven-3.0.5 <br />MAVEN_OPTS =&gt; -Xms256m -Xmx512m <br />PATH =&gt; %M2_HOME%\bin <br />打开终端，测试，输入mvn --version回车 <br />2 安装leiningen，leiningen是基于Clojure的项目构建工具，可以为Clojure项目打包解决项目依赖，这也是我们这次配置中要使用的主要工具。 <br />下载leiningen的windows压缩包和jar包（这里注意，不要用1.62的安装脚本安装，运行后面步骤时会出现错误），我下载的是： <br />leiningen-1.5.2-win.zip和leiningen-2.0.0-preview10-standalone.jar <br />下载网站：<a href="https://github.com/technomancy/leiningen/downloads">https://github.com/technomancy/leiningen/downloads</a> <br />下载完毕，leiningen-1.5.2-win.zip解压缩到本地目录。我放置在G:\server\lein，同时把leiningen-2.0.0-preview10-standalone.jar拷贝到这个文件夹下面 <br />添加环境变量：各位同学请输入自己的路径 <br />Path =&gt; G:\server\lein <br />LEIN =&gt; G:\server\lein <br />LEIN_JAR =&gt; G:\server\leiningen-2.0.0-preview10-standalone.jar <br />打开终端，测试，输入 lein version回车 <br />抛出一个异常上 stackoverflow 找到了处理方法 <a href="http://stackoverflow.com/questions/8863755/clojure-leiningen-and-classpath-on-windows">http://stackoverflow.com/questions/8863755/clojure-leiningen-and-classpath-on-windows</a> <br />打开终端，测试，输入 lein version回车 正常</p>

Leiningen是Clojure项目管理工具Leiningen is the easiest way to use Clojure，官网：http://leiningen.org/
 
 
1：首先下载Leiningen安装脚本：https://raw.githubusercontent.com/technomancy/leiningen/stable/bin/lein
 
 
2：将其保存为lein文件然后移动到/usr/bin/目录下面（Ubuntu14.0.4 LST 64Bit）
 
 
 
  
y@y:~$ sudo mv my_note/lein /usr/bin/
 
 
 
 
修改lein权限，让其可以执行：
 
 
 
  
y@y:/usr/bin$ chmod +x lein 
 
 
 
 
3：执行lein命令，进行安装：
 
 
 
  
y@y:~$ lein

It's possible your HTTP client's certificate store does not have the
correct certificate authority needed. This is often caused by an
out-of-date version of libssl. Either upgrade it or set HTTP_CLIENT
to turn off certificate checks:
  export HTTP_CLIENT="wget --no-check-certificate -O" # or
  export HTTP_CLIENT="curl --insecure -f -L -o"
It's also possible that you're behind a firewall haven't yet
set HTTP_PROXY and HTTPS_PROXY.
 
 
 
 
[由于国内网络原因不能访问下载链接]
首先清除：
 
 
 
  
y@y:~$ rm .lein/ -rf
 
 
 
 
采用VPN或代理进行联网，再次运行下载成功！

chmod 755 ~/bin/lein
 
 然后执行lein self-install
 

 
 
安装eclipse支持：
 
lein plugin install lein-eclipse 1.0.0
 
命令：
 
 
$ lein new [TEMPLATE] NAME # generate a new project skeleton

$ lein test [TESTS] # run the tests in the TESTS namespaces, or all tests

$ lein repl # launch an interactive REPL session

$ lein jar # package up the whole project as a .jar file

$ lein install # install a project

$ lein search [TERM] # find jars for your project.clj dependencies
