What is the problem?

Vercel 部署失败先看 build 日志再动手：Command exited with 1、Module not found、环境变量缺失、Output Directory 配错、Node 版本不符、构建超时、部署后 404、FUNCTION_INVOCATION_FAILED——8 个最常见 Vercel build 报错的真实原因和修复，附 Codex 辅助排查。

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.

Detailed steps

  1. `Command "npm run build" exited with 1` → 构建命令本身失败（见 ①）
  2. `Module not found` / `Can't resolve` → 找不到模块（见 ②）
  3. `Environment Variable ... references Secret which does not exist` / 运行时 undefined → 环境变量（见 ③）
  4. `No Output Directory named "public"/"dist" found` → 输出目录配错（见 ④）
  5. `Found invalid Node.js Version` / `engine` → Node 版本（见 ⑤）
  6. `Error: The build exceeded the maximum allowed runtime` → 构建超时（见 ⑥）

Commands or code

rm -rf node_modules .next && npm ci && npm run build

Risk notes

Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
