##  教程
直接升級 qt 到 5.x的最新版,或6.x  已5.x為例

目前5.x最新版沒有離線安裝了,采用線上安裝的方式 下載對應的文件

下載符合自己的平臺的版本 https://download.qt.io/archive/online_installers/4.5/

安裝時選自己需要的qt 版本,即可

## 舊項目升級內核
linux
- 刪除項目的QtWebEngine相關目錄 : rm ~/.local/share/項目名/QtWebEngine/

window
-  在 /users/用戶名/AppData/Local/項目名/QtWebEngine ,如 `C:\Users\CPJ\AppData\Local\com.xxx\即時通訊\QtWebEngine`

在重新編譯項目即可
