最近有个项目需要用到地图组件，底层使用的库包是"@amap/amap-jsapi-loader": "^1.0.1"，我下载的高德官网实例DEMO地址是https://a.amap.com/jsapi_demos/static/JSAPI_ReactAndVue/JSAPI_Vue3.zipz

这个版本是vue3+vue-cli+javascript的，底层使用的webpack打包的，不过项目真的有点老了，npm i就跑不起来了，有2处报错。

npm WARN deprecated querystring@0.2.0: The querystring API is considered Legacy. new code should use the URLSearchParams API instead.

        最终分析的结果就是package-lock.json中源的地址域名已经弃用了，我们可以直接删除掉该文件再执行npm i即可。然后NPM RUN SERVE 还是会报错：

opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ],
  library: 'digital envelope routines',
  reason: 'unsupported',
  code: 'ERR_OSSL_EVP_UNSUPPORTED'
}

        这个我本地的nodejs版本是v18.15.0，应该就是版本过高导致旧项目中的openssl无法正常兼容，解决的办法也是比较简单的，windows下添加环境变量名NODE_OPTIONS，变量值为--openssl-legacy-provider，修改完记得要重新开一个cmd终端才会生效。

        如果你的项目是vite2/3+vue3+ts的话，你再继续看下去。你直接用实例中的代码会报错@vue/reactivity not defined，这里有两种解决方案：

方式①：import {shallowRef} from '@vue/reactivity';//需要安装@vue/reactivity，pnpm i @vue/reactivity

方式②：import {shallowRef} from 'vue';

        解决完执行，还是空白页，地图内容还是不出来，查看开发者工具，还有一个报错：

        真是一脸懵逼，直接改版，使用script setup语法糖重新写了一遍代码，报错消失了，具体什么原因暂时不知道，感觉还是map没有定义好吧。具体代码可以下载：
