爭取用最短的話，將問題解決方法解釋清楚
一. idea打不開的問題
當我在破解idea的時候修改了help 里面上述文件 添加了下面一句話，導致程序打不開
然后可以使用 everything 搜索文件 idea64.exe.vmoptions 然后注釋掉如下語句就可以了
二. idea2020.2.3 for free
1. 首先附上官方安裝地址
IntelliJ IDEA：https://www.jetbrains.com/idea
GoLand：https://www.jetbrains.com/go
2. 以免費試用打開idea
安裝完成后，選擇 ”Evaluate for free“ 免費試用，點擊 “Evaluate” 進入 IDE 中，新建或打開一個項目
如果不能出現這個界面（可能是因為已經過試用期了），請打開壓縮包執行如下相應的重置腳本~
windows系統：reset_jetbrains_eval_windows.vbs
linux/mac系統：reset_jetbrains_eval_mac_linux.sh
3. 安裝配置agent的插件
安裝此款插件可以自動幫你配置 idea64.exe.vmoptions
1）打開插件中心 File -> Settings -> Manage Plugins Reposito，設置插件中心倉庫
2）設置倉庫地址：https://repo.idechajian.com
3）搜索關鍵字 BetterIntellij
4）重啟IDEA，打開注冊界面 Help -> Register，雙擊復制 添加如下激活碼
