不支持局部调用吗

不支持局部调用吗？ 我在局部组件里面调用，报错

部分代码：

<croppa v-model="myCroppa"></croppa>

import Croppa from 'vue-croppa';
import 'vue-croppa/dist/vue-croppa.css';

export default {
    components : {Header,Popup,Croppa},
    data() {
        return {
            myCroppa: {},
        }
    },
    mounted() {

    },
    methods: {
        avatarOpen() {
            this.myCroppa.generateBlob(
                blob => {
                // write code to upload the cropped image file (a file is a blob)
                },
                'image/jpeg',
                0.8
            ); // 80% compressed jpeg file
        },
    }
}

报错信息
