Angular 4.0Route "specified Page not found" cannot match

excuse me, I have asked you before, but it has not been solved.

error prompt: ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: "login"

after searching on the Internet for a long time, the answer is usually: set the route to path:", but this is currently the case.
also has several examples on stackoverflow, all of which are different. In the end, the "seemingly minor problem" was not solved.

    //LoginModule
    { path:'login',loadChildren:' /*login.module*/           
    login.module-sharpLoginModule' 
    }];
