git push 报错先看关键行再动手：rejected non-fast-forward、Permission denied publickey、密码认证已移除要用 PAT、unrelated histories、large files、no upstream——7 个最常见 git push 报错的真实原因和修复命令，附 Codex 工作流。

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. `! [rejected] ... (fetch first)` / `non-fast-forward` → 远程比你新（见 ①）
  2. `Permission denied (publickey)` → SSH 密钥（见 ②）
  3. `Support for password authentication was removed` → 要用 PAT（见 ③）
  4. `failed to push some refs` → 通常是 ① 的连带（见 ④）
  5. `refusing to merge unrelated histories` → 两个无关历史（见 ⑤）
  6. `remote: error: ... File ... is XXX MB; this exceeds GitHub's file size limit of 100 MB` → 大文件（见 ⑥）

Commands or code

git pull --rebase origin main
# 解决可能的冲突后
git push origin main

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.
