-----------------------------------------------

原因分析：

这个错误本质上不是 Next.js 的问题，而是 npm 本地缓存目录权限/损坏 了：

EEXIST + EACCES
npm cache 目录里文件冲突 + 没权限写入

你现在的路径是：

/Users/frank/.npm/_cacache/

这类问题在 Mac 上非常常见（通常是 sudo 装过 npm / node 导致权限混乱）。

---------------------------------------------

解决方案：

sudo chown -R $(whoami) ~/.npm

npm cache clean --force2

再运行：

npm install
