在attach进程的时候发生了错误
首先去oracle java (https://www.oracle.com/java/) 官网搜一下错误 看看有没有对应的解决办法
发现有个3个bug单 前两个都是对于MacOS的我们进去看下

官网推荐我们升级到jdk9 这个版本改bug已经被修复
我们直接使用下jdk16的环境 再来 试试
果然升级一下jdk就好了 。。。
再换个 jdk14试试
总结一下
MAC 遇到 Error attaching to process: sun.jvm.hotspot.debugger.DebuggerException: Can’t attach symbolicator to the process
建议升级jdk 版本的话 jdk9 以及jdk9以上 （这里测试了jdk 14 和 jdk16 ）
