vite 打包时：JavaScript heap out of memory（内存溢出）

出错原因分析：

执行命令 npm run build 时出现以下错误提示：

vite v3.2.7 building for production...                                                                        11:22:34

解决办法：

方法一、

node --max_old_space_size=102400 ./node_modules/vite/bin/vite.js build

方法二、

set NODE_OPTIONS=--max-old-space-size=4096
npm run build

方法三、

打开 package.json，在 scripts 部分修改 build 脚本：

{
  "scripts": {
    "build": "set NODE_OPTIONS=--max-old-space-size=4096 && vite build"
  }
}

方法四、

优化依赖和 Vite 配置
移除不必要的依赖：如果有不再使用的包或库，建议将其卸载，这样可以减少构建时的内存消耗。

npm uninstall <package-name>

分析并优化构建配置：使用 vite-plugin-analyzer 插件分析打包大小，并找出冗余或不必要的部分。

npm install vite-plugin-analyzer --save-dev

然后在 vite.config.js 中添加：

import { visualizer } from 'rollup-plugin-visualizer';

export default {
  plugins: [
    visualizer({ open: true }),
  ],
};
