# TypeError：'>' 不支持 'Version' 和 'str' 实例之间

- **ID:** `python/packaging-version-comparison-error`
- **领域:** python
- **类别:** type_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

直接将 packaging.version.Version 对象与字符串进行比较而未进行转换。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |
| 3.11 | active | — | — |
| 3.12 | active | — | — |

## 解决方案

1. **** (95% 成功率)
   ```
   from packaging.version import Version; v1 = Version('1.0'); v2 = Version('2.0'); print(v1 < v2)
   ```
2. **** (90% 成功率)
   ```
   from packaging.version import parse; print(parse('1.0') > parse('2.0'))
   ```

## 无效尝试

- **** — String comparison of versions (e.g., '1.10' > '1.9') is lexicographic and incorrect. (80% 失败率)
- **** — Equality may work but other comparisons still fail. (50% 失败率)
