页面刷新后无法工作的Angular4路由

Question

角4路由在页面刷新后不工作。以前起过作用。当前，当页面刷新路由要登录页面(默认路由)时，它应该停留在相同的路由上。

localhost:4200/dashboard，如果我们刷新这个页面，它将进入localhost:4200/login

我不知道项目中发生了什么变化，它突然停止工作了。请帮帮忙。

路由文件

    component: LoginComponent

export class AppRoutingModule { }

还有一件事，当我使用ng发球的时候，它会显示出角键警告。

您的全局角CLI版本(1.7.4)大于本地版本(1.7.3)。使用本地角度CLI版本。

若要禁用此警告，请使用"ng set --全局warnings.versionMismatch=false“。

Answer 1

1)由于您没有在刷新时登录(不可更改)，所以您的创作卫士正在重定向您登录。

2)关于CLI警告

在您的devDependencies中有：

"@angular/cli": "1.7.3",

在全局范围内，您已经安装了@角/ CLI @1.7.4，这就是CLI正在抱怨的原因。

如果您想在应用程序中保留@角/cli@1.7.3，并避免发出警告，则可以执行上述操作：

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
