Cannot read properties of undefined (reading 'ajax')

问题的原因是将axios当做Vue的插件使用了，这是错误的做法。正确的做法是通过导入axios并将其赋值给Vue的原型属性$ajax来使用。所以你需要修改代码如下：

import Vue from 'vue'
import axios from 'axios'
import Router from 'vue-router'
import ElementUI from 'element-ui'
Vue.use(ElementUI)
Vue.prototype.$ajax = axios

这样就可以正常使用axios的ajax方法了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
