中文步骤

  1. Restore the empty object from a backup or remote: git fetch origin refs/heads/main:refs/remotes/origin/main, then git fsck to verify
  2. Use git unpack-objects to rebuild objects from pack files if available
  3. As a last resort, clone the repo again and cherry-pick uncommitted changes from the broken clone

Dead Ends

Common approaches that don't work:

  1. Delete the empty object file manually 90% fail

    Breaks repository integrity; git will complain about missing objects and may refuse to operate.

  2. Run git fsck without fixing first 70% fail

    fsck only reports errors, does not repair; may lead to further confusion.

  3. Re-clone the entire repository 40% fail

    Overkill if only one object is corrupt; also loses uncommitted local changes.
