我們皇家理工的同學(xué)直接去教務(wù)系統(tǒng)把教育郵箱弄一下
然后到 https://www.jetbrains.com/zh/student/
申請一下免費用涩馆，然后全家桶全都免費用，真的正版

windows默認(rèn)安裝idea就行

windows hosts文件位置
C:\Windows\System32\drivers\etc\hosts
使用記事本打開鸳兽，但是請使用管理員權(quán)限打開惨好，不然沒法保存

mac/linux則是使用

sudo vim /etc/hosts

打開hosts文件
最后加一句

0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com

然后
