仅做个人备份

第一步：在访达中打开 软件源文件

打开 Finder(访达) --> Applications(应用程序) --> Goland(idea) --> Show Package Contents(显示包内容)

第二步：运行启动文件

按下图方式找到启动文件：Contents-->MacO-->goland， 双击运行

双击执行文件后，终端会显示具体错误信息:

报错指出 系统文件~/Library/Application Support/JetBrains/GoLand2020.2/goland.vmoptions 在加载-javaagent:/Documents/other/ideaConf/jetbrains-agent.jar 文件时出了问题。

直接打开该系统文件 vim ~/Library/Application Support/JetBrains/GoLand2020.2/goland.vmoptions， 内容如下：

-Xms128m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCompressedOops
-Dfile.encoding=UTF-8
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow

-XX:ErrorFile=$USER_HOME/java_error_in_goland_%p.log
-XX:HeapDumpPath=$USER_HOME/java_error_in_goland.hprof
-javaagent:/Documents/other/ideaConf/jetbrains-agent.jar

一方排查以后，自己电脑中-javaagent:/Documents/other/ideaConf/jetbrains-agent.jar 文件不存在了，软件加载不到，便启动失败。

解决方法

把该行注释掉，或者直接删除

-Xms128m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCompressedOops
-Dfile.encoding=UTF-8
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true

-XX:ErrorFile=$USER_HOME/java_error_in_goland_%p.log
-XX:HeapDumpPath=$USER_HOME/java_error_in_goland.hprof
# -javaagent:/Documents/other/ideaConf/jetbrains-agent.jar

保存文件后重启goland，可以正常启动了
