"Failed to resolve directive: transition" when trying to use a transition with vue-router - css-transitions

Question

I've got a vue app in which I'm using the vue-router.
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
let router = new VueRouter()
// Components
import App from './App.vue'
import Mapper from './components/Mapper/mapper.vue'
import ToDos from './components/Todos/ToDoApp.vue'
import Punchlist from './components/Punchlist/punchlist.vue'
// Transitions
Vue.transition('slide',{
enterClass: 'slideInRight',
leaveClass: 'slideOutRight'
})
// Redirects
router.redirect({
'*': 'punchlist'
})
// Mappings
router.map({
'/mapper': {
component: Mapper
},
'/todos': {
component: ToDos
},
'/punchlist': {
component: Punchlist
}
})
router.start(App, '#app')
I have a specific transition registered called slide that I would like to use when navigating between routes. In my App component I added the v-transition and transition-mode directives to the route-view:
<template>
<div class="container">
<h1>Component Gallery</h1>
<p>
<a class='btn btn-primary' v-link="{ path: '/punchlist' }">Punchlist</a>
<a class='btn btn-primary' v-link="{ path: '/todos' }">Todos</a>
<a class='btn btn-primary' v-link="{ path: '/mapper' }">Mapper</a>
</p>
<router-view v-transition="slide" transition-mode="out-in" :google-maps-api-key="googleMapsApiKey"></router-view>
</div>
</template>
When I try to run it, I get the console error:
[Vue warn]: Failed to resolve directive: transition (found in component: )
I've been reading through the docs and looking at examples but I can't figure out why it's erroring out when trying to resolve the binding.
Any ideas?

Transition is an attribute, not a directive. No v-:
<router-view transition="slide">
