错误：未捕获（承诺）：错误：无法匹配任何路由。 URL 段：“站点通知”

Question

我完全对这个错误感到困惑。我有一个非常基本的简单路由：

const routes: Routes = [
    {
        path: '', component: FrameDefaultComponent, pathMatch: 'full',
        children: [
            {path: '', component: SiteCalculatorComponent},
            {path: 'site-notice', component: SiteSiteNoticeComponent}
        ]
    },
];

当我在菜单中单击站点通知的菜单条目时，如下所示：

menuEntries = [
    {
        title: 'Calculator',
        url: '/'
    },
    {
        title: 'Site Notice',
        url: '/site-notice'
    }
];

然后我得到以下错误：

路由看起来像我每次使用的路由系统......但从未见过这个错误。

为父 route 制作 pathMatch : 'prefix' 或者您可以简单地删除它。

pathMatch: 'full' for parent route 将阻止 child routes 被执行。

const routes: Routes = [
    {
        path: '', component: FrameDefaultComponent, pathMatch: 'prefix',
        children: [
            {path: '', component: SiteCalculatorComponent},
            {path: 'site-notice', component: SiteSiteNoticeComponent}
        ]
    },
];
