 【解决办法】

   在macOS系统上设置环境变量：

    （参考博客： macOS系统 在～/.zshrc 中配置java环境变量： https://www.cnblogs.com/hf-cherish/p/5603147.html ）

1、首先检查一下 Java 是否安装

      

 2、根据以下提示输入命令：

    

 ## add the following line into the  .zshrc file ：
export JAVA_HOME=$(/usr/libexec/java_home)

     

 设置好了之后，输入 “ :wq” 退出。

      

检查Java_home是否设置成功：

      

输入的命令如下所示：

➜  ~ ## check all the available jdk
➜  ~ /usr/libexec/java_home -V
