根因分析

仓库为空（没有提交）或 HEAD 无效，导致 Git 无法将 'HEAD' 解析为修订版本。

English

The repository is empty (no commits) or HEAD is invalid, causing Git to fail to resolve 'HEAD' as a revision.

解决方案

  1. If the repository is empty, make an initial commit: git add . && git commit -m 'Initial commit'. This creates a valid HEAD.
  2. If HEAD is corrupted, reset it to a known state: git symbolic-ref HEAD refs/heads/main (if main branch exists) or reinitialize the repository: git init (backup data first).

无效尝试

常见但无效的做法:

  1. 80% 失败

    The error is about HEAD not being resolvable, not about a missing branch; checkout will fail with a different error.

  2. 70% 失败

    These commands may also fail with the same error if HEAD is invalid; they don't fix the underlying issue.
