Clojure学习笔记（2）安装Clojure构建工具 leiningen

1.在C盘下创建一个文件夹，并且命名为home_lein，然后把下载的lein.bat文件和leiningen-2.0.0-preview10-standalone.jar包放到C:\home_lein文件夹下。

如下图所示：

2.修改lein.bat脚本

将lein.bat脚本中的第27行的

if "x%LEIN_JAR%" == "x" set "LEIN_JAR=!LEIN_HOME!\self-installs\leiningen-!LEIN_VERSION!-standalone.jar"

修改为如下：

if "x%LEIN_JAR%" == "x" set "LEIN_JAR=C:\home_lein\leiningen-2.0.0-preview10-standalone.jar"

如下图所示：

3.为leiningen设置环境变量

截图	说明
	变量名：LEIN_HOME 变量值：C:\home_lein
	变量名：LEIN_JAR 变量值：C:\home_lein\leiningen-2.0.0-preview10-standalone.jar
	在Path中添加“;%LEIN_HOME%\;”

4.在DOS中输入命令行"lein"以验证leiningen是否已安装成功。

但根据运行反馈的信息，leiningen目前还没安装成功。运行结果如下图所示：

5.通过命令行进入c:\home_lein文件夹下执行命令行"lein.bat"。命令执行结果如下图所示：

6.根据上图运行反馈的信息，leiningen现在已经安装成功。

现在可以进入到c:\home_lein下通过DOS命令行执行“lein”命令。如下图所示：

7.现在也可以不用切换到c:\home_lein文件夹，直接就在DOS上通过输入“lein”命令来运行leiningen。如下图所示：

8.可以通过DOS命令行来检查目前所安装的leiningen的版本。如下图所示：

leiningen构建工具现在已经安装成功，接下来的学习笔记中将学习采用lein来创建clojure项目。这里要做一个笔记：

因为整个安装过程的截图我保存在word文档中，如果直接复制word文档中的图片黏贴到osc的编辑器中，保存博文之后是无法显示图片的。所以百度了一下怎么把word中的图片还原保存成单个图片，方法如下：

将打开的word文档另存为网页，在word文档的所在位置下会生成一个跟word文档同名的文件夹，里页就有之前保存在word文档中的所有图片。
