What is the problem?
新手用 Codex 接触 Next.js 或 Node.js 项目时,npm install 报错很常见。本文用可执行步骤解释如何判断 Node 版本、依赖冲突、网络和权限问题,避免在没有把握时承诺客户。
Quick solution
Treat this as a Codex troubleshooting issue. First confirm the environment, inputs, permissions, logs, and delivery boundary. Then use the linked deep guide for the full checklist before changing production code or promising a result.

- 保存完整报错,不要只截最后一行。把终端输出复制到一个文本文件,保留命令、路径和时间。
- 查看版本:
- 查看项目要求。打开 `package.json`,找 `engines` 字段;查看 `README` 是否写了 Node 版本。
- 如果版本不匹配,优先切换到项目要求的 LTS 版本。新手不要在客户项目里随意升级大量依赖。
- 如果是依赖冲突,先尝试:
- 如果是网络问题,稍后重试,或确认 npm registry 是否可访问。
