# 运行时错误：锁未获取

- **ID:** `python/asyncio-lock-not-acquired`
- **领域:** python
- **类别:** runtime_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

在未持有的asyncio.Lock上调用lock.release()。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 3.7 | active | — | — |
| 3.8 | active | — | — |

## 解决方案

1. **** (100% 成功率)
   ```
   async with lock: ...
   ```
2. **** (95% 成功率)
   ```
   await lock.acquire(); try: ... finally: lock.release()
   ```

## 无效尝试

- **** — acquire() is a coroutine; must be awaited. (90% 失败率)
- **** — It's a race condition; the lock may be released between check and release. (70% 失败率)
