why I'm getting "UNMET PEER DEPENDENCY" error in angular 2

I'm trying to install angular2-flash-messages to my angular-src, not to the root. then I tried with npm install angular2-flash-messages. then it returns this,

├── UNMET PEER DEPENDENCY @angular/[email protected]
└── [email protected]

then I tried to resolve this with installing rxjs and angluar/cli globally. But it didn't work. How do I fix this?

there is a warning : npm WARN [email protected] requires a peer of @angular/core@^4.0.0 but none was installed.

You try import by:

import {FlashMessagesModule} from 'angular2-flash-messages/module';

constructor(
....
public flashMessage:FlashMessagesService
) { }

logout() {
    ...
    this.flashMessage.show('Your message', {cssClass: 'alert-success', timeout: 3000});
}

This working for me.

It means that that version of angular2-flash-messages uses @angular/core version 4.0.0^. Your project might still work but that's the recommended version. If there are any breaking changes in the peer library your app might crash so it's recommended to install the correct peer dependencies.
