main.js文件代碼如下：

import?Vue?from?'vue'

import?App?from?'./App.vue'

import?router?from?'./router'

import?'lib-flexible'

import?'./common/stylus/index.styl'

import?Vant?from?'vant';

import?'vant/lib/index.css';

import?'./common/js/rem'

import?qs?from?'qs'

import?axios?from?'axios'

Vue.use(Vant);

//import?Http?from?'./api/http'

Vue.config.productionTip?=?false

Vue.prototype.$axios?=?axios

//把http掛在到vue實例上

//Vue.prototype.$Http?=?Http

new?Vue({

??router,

??render:?h?=>?h(App)

}).$mount('#app')

誰幫我看看是怎么回事？謝謝。
