I use Vue 2

In template

<image-picker field="img"
	v-model="fImagePick"
	langType="ru"
	@crop-success="cropSuccess()"
	@crop-upload-success="cropUploadSuccess()"
	@crop-upload-fail="cropUploadFail()"
	:url="API.SERVER+'user/tag/add/'"
	:params="imgparams"
	:width="300"
	:height="300">
</image-picker>

In script

import ImagePicker from 'vue-image-crop-upload';
//undefined too
//import ImagePicker from ';vue-image-crop-upload/upload-2.vue'
...
cropSuccess(imgDataUrl, field){
	console.log('-------- crop success --------');
	console.log(imgDataUrl);
	console.log(field);
	this.image = imgDataUrl;
}
...

Result

-------- crop success --------
undefined
undefined
