执行gulp 后 提示Cannot find module 'vue' ?

Question

Error: Can't walk dependency graph: Cannot find module 'vue' from 'D:\xxxx\src\assets\js\main.js'

gulpfile.js 配置

main.js中内容

import { createApp } from 'vue';createApp({  data() {    return {      showRule: false    }  },  created() {    console.log("created");  },  methods: {    unfoldRule() {      this.showRules = true;    }  }}).mount('#app')console.log("start watch");

vue 已经在 html 中通过cdn 引入

Answer 1

你自己捋捋,
在vue在html中通过cdn引入的话,
你咋能通过import { createApp } from 'vue'拿到呢?
