cesium1.82运行 Error: Cannot find module ‘express‘

从官网下载的cesium1.82初始运行项目报错Cannot find module 'express'

一、问题

缺少依赖，然后执行npm install

出现以下错误：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: cesium@1.82.0

二、解决问题

找到pack.json文件

删除"rollup-plugin-uglify": "^6.0.4",

增加"rollup-plugin-terser": "^7.0.2",

修改引用

删除// const rollupPluginUglify = require("rollup-plugin-uglify");

增加const rollupPluginUglify = require("rollup-plugin-terser");

重新执行npm install ---安装成功

node server.cjs 执行成功
