https://lbs.amap.com/api/javascript-api/reference-amap-ui/mass-data/pathsimplifier/
1、在vue 项目中的 main.js 中加入
import VueAMap from 'vue-amap'
/* 高德地图的引入 */
VueAMap.initAMapApiLoader({
key: '5ab20b9b8aad8959b51d74f0cc3bc0ce',
plugin: ['AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType'],
uiVersion: '1.0', // ui库版本，不配置不加载,
v: '1.4.4'
});
Vue.use(VueAMap);
2、在 index.html 中加入
<script src="http://webapi.amap.com/maps?v=1.4.6&key=e598f982202f82de4802cefed15fe8e5"></script> <script src="//webapi.amap.com/ui/1.0/main.js?v=1.0.11"></script>
注意：其中的 key 需要自己高德官网去注册获得。
3、这个时候 要把 高德组件加入 项目
在 terminal 执行 npm install --save vue-amap
