最近跟著老師做專案，需要用到idea，但是學生黨沒錢，還請見諒！下面分享一下方法！

1、去官網下載並安裝 idea，下載要收費的版本     地址：https://www.jetbrains.com/idea/download

2、下載破解(crack) jar 包 地址 http://idea.lanyus.com/jar/JetbrainsCrack-2.7-release-str.jar

如果失效，去下面這個網站 http://idea.lanyus.com 自行下載

3、下載好了的 crack jar包 放到 idea 的 bin 目錄下

如下圖所示

4、修改 bin 目錄下的 idea.exe.vmoptions和idea64.exe.vmoptions 檔案（由於不清楚哪個發揮作用，建議都修改了）

把 idea.exe.vmoptions和 idea64.exe.vmoptions  檔案加一行如下的配置，根據你儲存的檔名路徑變換

                          -javaagent:../bin/JetbrainsCrack-3.1-release-str.jar

如下圖所示：

5、在 hosts 檔案裡面新增如下配置（win10的路徑為：C:\Windows\System32\drivers\etc）

                                        0.0.0.0 account.jetbrains.com

修改hosts檔案的方法：

由於 hosts 檔案屬性系統檔案，因此需要管理員許可權才能對其進行修改。先將hosts檔案複製到桌面，這時就不需要管理員許可權了，因此可以對其進行修改了，等修改之後，在將其拖回原目錄，替換就可以啦！

修改後如下圖所示：
