SDKMAN 软件开发工具包管理器的安装非常简单，只需要打开终端，执行：

$ curl -s "https://get.sdkman.io" | bash

就OK了，输出类似如下：

然后根据命令输出最后的提示执行类似命令：

source "/Users/aven/.sdkman/bin/sdkman-init.sh"

注意：你在命令输出中到的提示命令可能与我的不完全相同，至少我们的用户名不相同。

执行完成之后，“sdk”命令就可以使用了：

$ sdk==== BROADCAST =================================================================* 29/07/17: Scala 2.12.3 released on SDKMAN! #scala* 27/07/17: Springboot 1.5.6.RELEASE released on SDKMAN! #springboot* 26/07/17: Springboot 2.0.0.M3 released on SDKMAN! #springboot================================================================================Usage: sdk <command> [candidate] [version]       sdk offline <enable|disable>   commands:       install   or i    <candidate> [version]       uninstall or rm   <candidate> <version>       list      or ls   [candidate]       use       or u    <candidate> [version]       default   or d    <candidate> [version]       current   or c    [candidate]       upgrade   or ug   [candidate]       version   or v       broadcast or b       help      or h       offline           [enable|disable]       selfupdate        [force]       flush             <candidates|broadcast|archives|temp>   candidate  :  the SDK to install: groovy, scala, grails, gradle, kotlin, etc.                 use list command for comprehensive list of candidates                 eg: $ sdk list   version    :  where optional, defaults to latest stable if not provided                 eg: $ sdk install groovy

否则你将看到以下提示：

$ sdk-bash: sdk: command not found

找不到“sdk”命令。

好了，就是安装命令输出所说，Enjoy!!!
