leiningen安装记录

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out-of-date version of libssl.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.

classpath           Print the classpath of the current project.
clean               Remove all files from project's target-path.
compile             Compile Clojure source into .class files.
deploy              Build and deploy jar to remote repository.
deps                Download all 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 the 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.

release             Perform :release-tasks.
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 a -main function with optional command-line arguments.
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.

google了一番原来是leiningen2.4.3的一个BUG:https://github.com/technomancy/leiningen/issues/1625

解决方法：将其回退到2.4.2版
