Jest with vuejs import es6失败语法错误:意外标记<

import ContactForm from "../components/Contact/ContactForm.vue";
import { mount } from '@vue/test-utils'

describe("Contact Form", () => {

});

但是现在我得到一个错误SyntaxError:在import ContactForm中出现意外的token<

<template>
    my form is here
</template>
<script>
    export default{
        data:()=>({
            contact_form:{
                first_name:'',
                last_name:'',
                email:'',
                message:'',
            }
        }),
        methods:{
            ContactUs(){
               //stuff
            }
        }
    }
</script>
