最近开始学习cesium，尝试在在vue项目中安装cesium，一开始报了许多错误，终于尝试成功，记录一下过程。

创建vue项目

cd到指定目录，create 'your vueProj name'，接下来按照需求配置，空格键勾选，回车创建项目

安装cesium

npm install cesium@1.95.0 -s

安装webpack

npm install copy-webpack-plugin@10.2.4

安装webpack所需loader

npm install @open-wc/webpack-import-meta-loader

配置vue.config.js

const {defineConfig} = require('@vue/cli-service')
const CopyWebpackPlugin = require("copy-webpack-plugin");
const webpack = require("webpack");
const path = require("path");
 
let cesiumSource = "node_modules/cesium/Source";
let cesiumWorkers = "Workers";
module.exports = defineConfig({
  transpileDependencies: true,
  lintOnSave: false,
  configureWebpack: {
    externals: {
      'cesium': 'Cesium',
    },
    output: {
      sourcePrefix: " ", 
    },
    amd: {
      toUrlUndefined: true, 
    },
    resolve: {
      extensions: ['.js', '.vue', '.json'],
      alias: {
        "@": path.resolve("src"),
        cesium: path.resolve(__dirname, cesiumSource),
      }
    },
    plugins: [
      new CopyWebpackPlugin({
        patterns: [
          {from: path.join(cesiumSource, cesiumWorkers), to: "Workers"},
          {from: path.join(cesiumSource, "Assets"), to: "Assets"},
          {from: path.join(cesiumSource, "Widgets"), to: "Widgets"},
          {from: path.join(cesiumSource, "ThirdParty/Workers"), to: "ThirdParty/Workers"}
        ]
      }),
      new webpack.DefinePlugin({
        CESIUM_BASE_URL: JSON.stringify("./"),
      }),
    ],
    module: {
      unknownContextCritical: false,
      unknownContextRegExp: /\/cesium\/cesium\/Source\/Core\/buildModuleUrl\.js/,
      rules: [
        {
          test: /\.js$/,
          use: {
            loader: '@open-wc/webpack-import-meta-loader',
          },
        },
      ]
    },
  },
  devServer: {
    hot: true,
    open: true,
    // 代理
    proxy: {
      '/api': {
        target: 'http://localhost:8888/',
        changeOrigin: true,
        ws: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    },
    port: 8080,
  }
})

main.js中导入cesium的css

import 'cesium/Widgets/widgets.css';

App.vue 配置style

html,body,#cesiumContainer {
  width: 100%;
  height: 100%;
  margin: 0;
  padding: 0;
  overflow: hidden;
}

修改HelloWorld.vue

<template>
  <div id="cesiumContainer">
  </div>
</template>
<script>
import * as Cesium from 'cesium/Cesium'
export default {
  name: 'HelloWorld',
  mounted(){
  this.initCesium()
  },
  methods:{
    initCesium:function (){
      Cesium.Ion.defaultAccessToken = 'token'
      let viewer = new Cesium.Viewer('cesiumContainer')
    }
  }
}
</script>
<style scoped>
 
</style>
