3.修改配置文件
进入到项目界面后，点击Idea最上面的菜单栏中的 “Help” -> “Edit Custom VM Options …”，如果提示是否要创建文件，请点”Yes”。
在打开的vmoptions编辑窗口末行添加：-javaagent:你idea的安装目录\jetbrains-agent.jar
"C:\Users\llskj\AppData\Roaming\JetBrains\IntelliJIdea2020.1\idea64.exe.vmoptions"
-javaagent:你idea的安装目录\jetbrains-agent.jar
-javaagent:C:\key\jetbrains-agent.jar 目录不能有空格或中文，
# custom IntelliJ IDEA VM options
-Xms128m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-XX:CICompilerCount=2
-Dsun.io.useCanonPrefixCache=false
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
-Djdk.attach.allowAttachSelf=true
-Dkotlinx.coroutines.debug=off
-Djdk.module.illegalAccess.silent=true
-javaagent:C:\key\jetbrains-agent.jar
请仔细检查补丁路径是否正确，如果错误则会出现Idea打不开的情况，这时候可以删除用户配置目录下的Idea文件夹:
windwos：C:\Users\llskj\AppData\Roaming\JetBrains
修改完配置文件之后重启Idea
4.输入激活码
