一.官网下载安装包（点击安装即可）
二.破解(补丁破解)
1）步骤一:将补丁的文件放到安装IDEA路径的bin目录下
2）步骤二:找到idea.exe.vmoptions和idea64.exe.vmoptions。
在两个文件最后分别加上（如图）
-javaagent:D:\IDEA\IntelliJ IDEA 2018.1.6\bin\JetbrainsCrack-2.9-release-enc.jar
3)步骤三：修改Activation Code
重启Intellij IDEA，在Activation Code输入：
ThisCrackLicenseId-{ "licenseId":"ThisCrackLicenseId",
"licenseeName":"你想要的用户名",
"assigneeName":"",
"assigneeEmail":"随便填一个邮箱(我填的:[email protected])",
"licenseRestriction":"For This Crack, Only Test! Please support genuine!!!", "checkConcurrentUse":false, "products":[
{"code":"II","paidUpTo":"2099-12-31"},
{"code":"DM","paidUpTo":"2099-12-31"},
{"code":"AC","paidUpTo":"2099-12-31"},
{"code":"RS0","paidUpTo":"2099-12-31"},
{"code":"WS","paidUpTo":"2099-12-31"},
{"code":"DPN","paidUpTo":"2099-12-31"},
{"code":"RC","paidUpTo":"2099-12-31"},
{"code":"PS","paidUpTo":"2099-12-31"},
{"code":"DC","paidUpTo":"2099-12-31"},
{"code":"RM","paidUpTo":"2099-12-31"},
{"code":"CL","paidUpTo":"2099-12-31"},
{"code":"PC","paidUpTo":"2099-12-31"} ],
"hash":"2911276/0",
"gracePeriodDays":7,
"autoProlongated":false}
然后……就成功了。到2099年，你可能要玩一辈子编程了。
