Updated existing /Users/aven/.zshrc

All done!

Please open a new terminal, or run the following in the existing one:

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

Then issue the following command:

    sdk help

Enjoy!!!

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!!!
