pnpm create vite demo_cesium

2、进入项目安装依赖 

cd demo_cesium
pnpm install

import vue from '@vitejs/plugin-vue'
import cesium from 'vite-plugin-cesium'// https://vitejs.dev/config/
export default defineConfig({plugins: [vue(),cesium()],
})

<template><div id="cesiumContainer"></div>
</template>
<script setup>
import { onMounted } from 'vue'
import * as Cesium from 'cesium'
onMounted(() => {Cesium.Ion.defaultAccessToken = '' //改为自己申请的tokennew Cesium.Viewer('cesiumContainer')   
})
</script>
<style scoped></style>
