页面刷新后Angular4路由不工作

页面刷新后，Angular 4路由不工作。它以前工作过。 当前，当页面刷新路由要进入登录页面（默认路由）时，它应该保持在同一路由上

localhost:4200/dashboard如果我们刷新此页面，它将转到localhost:4200/login

我不知道项目发生了什么变化，突然停止了工作。请帮忙

路由文件

还有一件事，当我使用ng serve时，它会显示角度cli警告

您的全局Angular CLI版本（1.7.4）高于本地版本 版本（1.7.3）。使用本地CLI版本

要禁用此警告，请使用“ng set--global warnings.versionMismatch=false”。

1） 您的authguard正在将您重定向到登录，因为您在刷新时未登录（中间登录）

2） 关于CLI警告

在您的DevDependence中，您有：

"@angular/cli": "1.7.3",

在全球范围内，您已安装@angular/cli@1.7.4 这就是CLI抱怨的原因

如果你想保持@angular/cli@1.7.3在应用程序中，避免出现警告，您可以执行以下操作：

ng set --global warnings.versionMismatch=false 

或者全局安装相同的版本

npm i -g @angular/cli@1.7.3
