o.default.polylineDecorator is not a function

[wishinghand]

Anyone seen this error crop up? Everything was working fine until it wasn't. I haven't upgraded any Leaflet packages, though I recently did update Vue and vue-template-compiler to match each other's version. Everything on my Leaflet map works fine except for the arrowheads that I'm drawing with this polyline decorator. Error is as follows:

[Vue warn]: Error in mounted hook: "TypeError: o.default.polylineDecorator is not a function"

I'm importing this package like so:
import GateArrow from 'vue2-leaflet-polylinedecorator'

and using it here:

<gate-arrow
  :paths="gate.coordinates"
  :patterns="arrowPattern"
/>

Where paths is a two pairs of coordinates for a line segment to be the arrow body, and patterns is the arrowhead, defined as:

arrowPattern: [{
  offset: '100%',
  repeat: 0,
  symbol: L.Symbol.arrowHead({
    pixelSize: 15,
    polygon: false,
    pathOptions: { stroke: true }
  })
}]

Sorry, forgot that important detail.
Vue: 2.5.22
Vue2Leaflet: 1.0.2
vue2-leaflet-polylinedecorator: 2.0.1

Switching from Yarn to NPM seemed to have solved this, though no idea why it did.

Same here, guys. Using yarn on this case:
