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。
http://blog.csdn.net/sheismylife/article/details/8331287

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：

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！
