Vue运行报错： __WEBPACK_IMPORTED_MODULE_0_babel_runtime

Question

Vue报错：
__WEBPACK_IMPORTED_MODULE_0_babel_runtime_core_js_promise___default.a is not a constructor
Promise未定义错误

function getCart() {
        const p = new Promise((resolve, reject) => {
            const token = getToken();
            request_8044({
                method: 'get',
                url: '/yryd/shoppingCart/queryShoppingCart',
                withCredentials: true,
                params: {
                    token: token
                }
            }).then(( { data }) => {
                state.good_list = data
                for(let item of data){
                    state.cart_list.push(item.bookName)
                }
                resolve()
            })
        })
        p.then(() => {
            getImg()
        })
