安装shadcn包遇MODULE_NOT_FOUND错误，常规修复无效求解决

问题重现 #

执行安装命令：

pnpm dlx shadcn@latest add accordion

触发以下错误：

ERR_PNPM_RECURSIVE_EXEC_FIRST_FAIL  Command "cache" not found
node:internal/modules/cjs/loader:1275
  const err = new Error(`Cannot find module '${request}'`);
              ^

}

Node.js v23.3.0

已尝试以下操作但无效：

• 清理pnpm存储并重装依赖：

  pnpm store prune
  rm -rf node_modules pnpm-lock.yaml
  pnpm install
  

• 手动安装缺失包：

  pnpm add @jridgewell/gen-mapping
  pnpm add -D @jridgewell/gen-mapping
  

解决方案 #

尝试以下步骤：

1. 彻底清除pnpm dlx独立缓存
   dlx缓存与pnpm主存储分离，直接删除dlx缓存目录：

   rm -rf /Users/XXX/Library/Caches/pnpm/dlx
   

   替换XXX为你的实际系统用户名。

2. 切换Node.js稳定版本
   Node.js v23为开发版本，存在兼容性风险，切换至LTS稳定版（如v20.x）后重试：

   # 若使用nvm版本管理工具
   nvm install 20
   nvm use 20
   

3. 指定shadcn具体版本安装
   避开latest标签的潜在兼容性问题，使用稳定版本号：

   pnpm dlx shadcn@1.0.4 add accordion
   

4. 强制跳过缓存执行命令
   禁用缓存重新拉取所有依赖：

   pnpm dlx --no-cache shadcn@latest add accordion
