build后IE中不能浏览，字体文件和icon图标路径不正确，URL中#不能去掉问题

build打包后问题太多要解决，不能在IE中预览，login页面点击登录不能跳转到home页面（npm run dev可以跳转），字符文件和icon图标找不到，URL不能开启mode: 'history'去掉#，期待解决。

Start by comparing the built application with the working npm run dev behavior, focusing on IE preview, login navigation, font and icon paths, and the URL hash. Reproduce each reported problem from the build output and identify whether the build configuration or runtime routing is responsible. Done means the built application previews in IE, login reaches home, assets load, and history mode removes the hash.
