axios报错

[Vue warn]: Error in mounted hook: "TypeError: Cannot read properties of undefined (reading 'get')"

found in

vue.runtime.esm.js?2b0e:1897 TypeError: Cannot read properties of undefined (reading 'get')
    at VueComponent.http (About.vue?c330:18:1)
 

我在main里这样写

import Vue from 'vue'

import App from './App.vue'

import router from './router'

import store from './store'

import Vant from 'vant';

import 'vant/lib/index.css';

import axios from 'axios'

Vue.prototype.$axios=axios

Vue.use(Vant);
 

Vue.config.productionTip = false

new Vue({

    router,

    store,

    render: h => h(App)

}).$mount('#app')

照样报错
