Input Code and steps to reproduce
App.js

<template>
  <div id="app">
		<carousel :per-page="1" :custom-slide-width="1">
			<slide>
				Slide 1 Content

				Slide 2 Content
			</slide>
		</carousel>
	</div>
</template>

<script>
import { Carousel, Slide } from 'vue-carousel'

export default {

}
</script>

Expected behavior/code
Doing a yarn link should allow me to use vue-carousel in a local project.

Hey @rkomiyama, yarn has an open issue that's likely effecting this. I can recreate your issue on my local if I use yarn link, but it works fine if instead I point to my local directory with node_modules installed in my package json (i.e vue-carousel: link: ../path/to/vue-carousel)

Since it's likely that this is an issue on yarns end, I'll close this. Feel free to reopen of make a comment here if you feel otherwise!

@quinnlangille I'm still getting the same warnings even with npm link. There might be an issue with vue create, but I'm not sure how relevant it is to this issue (vuejs/vue-cli#1494).

Edit: I just tried it using vue init and that seemed to work.
