你配置vue路由了么？比如你的页面结构式一个App.vue和一个main.mp.js的话。

你需要在mimp.js中配置vue路由

如：

import App from "./App.vue";

import "@/minmain.mp";

import Vue from "vue";

import Router from "vue-router";

import A from '@/pages/A/a.vue'

import B from '@/pages/B/b.vue'

export default function createApp() {

  const container = document.createElement("div");

  container.id = "app";

  document.body.appendChild(container);

  window.onload = function () {

    document.documentElement.style.fontSize =

      wx.getSystemInfoSync().screenWidth / 16 + "px";

  };

  Vue.use(Router);

  const router = new Router({

    mode: "hash",

    routes: [

      { path: "/a", component: A},

      { path: "/b", component:B},

    ]

  });

  return new Vue({

    el: "#app",

    router,

    render: h => h(App)

  });

}

取消async试试
