论语有曰：工欲善其事必先利其器。作为一名前端小白，用不习惯VSCode的小伙伴尤其需要破解完成的webStorm，经过半天的研究，该方法能够满足需要。我安装的是webStorm2019.2.3版本，破解步骤如下：【不需要修改host】
1.打开已经安装好的 webstorm , 我们选择 30 天免费试用，先进去再说：
2.成功进入 webstorm 以后，我们随便创建一个项目/或者打开个旧的项目，点击顶部的 Help 菜单 -> Edit Custom VM Option
3.打开后，我们在最后一行添加如下配置：
-javaagent:D:jetbrains-agent.jar ，点击保存。
4.在webStorm文件夹下的bin目录里放入破解的jar包。
5.在help-register下填写激活码
