1、

从http://idea.lanyus.com/中圈出位置下载一个jar包

2、

找到golang安装目录，将下载的JetbrainsIdesCrack-3.4-release-enc.jar复制到GoLand的bin目录下

找到bin目录下两个vmoptions文件，idea.exe.vmoptions和idea64.exe.vmoptions，用记事本打开，在最后一行都加上

-javaagent:（JetbrainsIdesCrack-3.4-release-enc.jar所在地址）如我的：

-javaagent:D:\Program Files (x86)\GoLand 2018.3.2\bin\JetbrainsIdesCrack-3.4-release-enc.jar

3、

重启GoLand,复制以下内容到Acrivation code（安装时点击或在GoLand界面点help>Register）中的空白处
