Angular 13 和 Bootstrap 5 | UI 添加路由时消失

Angular 13 and Bootstrap 5 | UI vanishes when routes are added

我一直在开发一个网站,但一直无法超越导航。我遇到的问题是,当我设置路线时,整个 UI 消失并且不会加载。我无法找到任何关于此的信息或它可能发生的原因,但将不胜感激任何形式的帮助或指导!

在你的app-routes.module.ts中,你不应该在路由路径定义上使用/;即,使用 home 而不是 /home.

在您的 navi.component.html 中,Angular 中的 href 指令刷新了页面。请在 nav 栏的 a 标签中用 routerLink 指令更新所有 href 指令。
