下載了官網(wǎng)最新的goland安裝包，安裝完成之后，goland卻無(wú)法打開(kāi)了。

一番排查之后，發(fā)現(xiàn)是之前安裝的版本有一些殘留的配置項(xiàng)。配置項(xiàng)中有些文件的已經(jīng)不存在了，需要去手動(dòng)清理。

解決方法

第一步：在訪(fǎng)達(dá)中打開(kāi) 軟件源文件

打開(kāi) Finder(訪(fǎng)達(dá)) --> Applications(應(yīng)用程序) --> Goland(idea) --> Show Package Contents(顯示包內(nèi)容)

第二步：運(yùn)行啟動(dòng)文件

按下圖方式找到啟動(dòng)文件：Contents-->MacO-->goland， 雙擊運(yùn)行

雙擊執(zhí)行文件后，終端會(huì)顯示具體錯(cuò)誤信息:

報(bào)錯(cuò)指出 系統(tǒng)文件~/Library/Application Support/JetBrains/GoLand2020.2/goland.vmoptions 在加載-javaagent:/Documents/other/ideaConf/jetbrains-agent.jar 文件時(shí)出了問(wèn)題。

直接打開(kāi)該系統(tǒng)文件 vim ~/Library/Application Support/JetBrains/GoLand2020.2/goland.vmoptions， 內(nèi)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，自己電腦中-javaagent:/Documents/other/ideaConf/jetbrains-agent.jar 文件不存在了，軟件加載不到，便啟動(dòng)失敗。

解決方法

把該行注釋掉，或者直接刪除

-Xms128m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseCompressedOops
-Dfile.encoding=UTF-8
-XX:+UseConcMarkSweepGC

-XX:HeapDumpPath=$USER_HOME/java_error_in_goland.hprof
# -javaagent:/Documents/other/ideaConf/jetbrains-agent.jar

保存文件后重啟goland，可以正常啟動(dòng)了
