# 致命：路径 '<子模块路径>' 未指向有效的提交：<哈希>

- **ID:** `git/submodule-commit-not-found`
- **领域:** git
- **类别:** config_error
- **验证级别:** ai_generated
- **修复率:** 82%

## 根因

子模块引用指向了一个在子模块仓库中不存在的提交哈希，通常是由于在子模块中进行了强制推送或变基而没有更新父仓库。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| git 2.40.1 | active | — | — |
| git 2.41.0 | active | — | — |
| git 2.42.2 | active | — | — |

## 解决方案

1. ```
   Update the submodule reference to a valid commit: 'cd <submodule-path> && git fetch origin && git checkout <valid-hash>', then commit the change in the parent repo
   ```
2. ```
   If the missing commit is from a force-push, ask the submodule maintainer to restore it, or update the parent to point to a different commit using 'git submodule set-url' and 'git add'
   ```

## 无效尝试

- **** — This updates to the latest remote commit, not the missing hash; it changes the submodule version and may break compatibility with the parent project. (60% 失败率)
- **** — Re-adding the submodule requires the same commit hash; if the hash is missing from the remote, the error persists. (50% 失败率)
