有了网站模板 还要怎样做深圳谷歌推广公司
准备工作
自动创建 package.json 文件
npm init -y
安装Three.js 3D 图形库，安装现代前端构建工具Vite（用于开发/打包）
npm install three vite
启动 Vite 开发服务器（推荐）（正式项目开发）
npm run dev
启动 Vite 开发服务器（快速测试或临时使用）
npx vite
npm init -y
说明：
- 自动创建 package.json 文件
- -y 参数表示接受所有默认选项
- 生成包含项目基本信息、依赖和脚本的基础配置文件
npm install three vite 说明： - three - 安装 Three.js 3D 图形库（当前项目核心依赖）
- vite - 安装现代前端构建工具（用于开发/打包）
- 安装后会生成 node_modules 目录和 package-lock.json
