安装过程如下:

https://raw.github.com/technomancy/leiningen/preview/bin/lein
2. 复制到/usr/bin目录下,并允许执行
[plain] view plain copy print ?
- mv lein /usr/bin/
- [email protected]:~/Downloads# chmod +x /usr/bin/lein

- classpath Write the classpath of the current project to output-file.
- clean Remove all files from project's target-path.
- compile Compile Clojure source into .class files.
- deploy Build jar and deploy to remote repository.
- deps Show details about dependencies.
- do Higher-order task to perform other tasks in succession.
- help Display a list of tasks or help for a given task.
- install Install current project to the local repository.
- jar Package up all the project's files into a jar file.
- javac Compile Java source files.
- new Generate project scaffolding based on a template.
- plugin DEPRECATED. Please use the :user profile instead.
- pom Write a pom.xml file to disk for Maven interoperability.
- repl Start a repl session either with the current project or standalone.
- retest Run only the test namespaces which failed last time around.
- run Run the project's -main function.
- search Search remote maven repositories for matching jars.
- show-profiles List all available profiles or display one if given an argument.
- test Run the project's tests.
- trampoline Run a task without nesting the project's JVM inside Leiningen's.
- uberjar Package up the project files and all dependencies into a jar file.
- upgrade Upgrade Leiningen to specified version or latest stable.
- version Print version for Leiningen and the current JVM.
- with-profile Apply the given task with the profile(s) specified.
- Run lein help $TASK for details.

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:
[plain] view plain copy print ?
- $ 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:
[plain] view plain copy print ?
- user=> (+ 1 2)
- 3
能够运行。注意=>左边的user代表当前的namespace.
