carousel warnings about hammer.js

[CarinaCLH]

Version

1.8.0

Environment

windows10, angular 6.2.4

Reproduction link

https://ng-zorro-antd-start-lc5lqb.stackblitz.io/

Steps to reproduce

1. copy the code about carousel to my website;
2. get warings, like " The 'pan' event cannot be bound because Hammer.JS is not loaded and no custom loader has been specified."
3. I just set [nzEnableSwipe]="false";
4. I still get warnings
   
5. I think for pc users, we don't need to import Hammer.JS to support gesture, so how can i get out of those warnings?

What is expected?

without any warnings about Hammer.JS

What is actually happening?

have warnings

Other?

Because of this line:

ng-zorro-antd/components/carousel/nz-carousel.component.html

Line 3 in d9db523

(swipeleft)="swipe('swipeleft')" (swiperight)="swipe('swiperight')" (pan)="swipeInProgress($event);">

Supporting hammer.js is a built-in feature of Angular. I will try to silent it.

Thank you for your reply and your great job.

I have the same issue and swipe is not working in the carousel. Should I install hammerjs (at least before the fix)?
Why it's not a part of the project's dependencies?

@vahidvdn Recently, we refactored the component and hammer.js will be required no longer soon.
