请求的包版本在PyPI上不存在或索引URL无法访问。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |

| 3.9 | active | — | — |

## 解决方案

1. **Specify an existing version or use latest** (95% 成功率)
   ```
   pip install tensorflow==2.15.0
   ```
2. **Check package availability on PyPI** (90% 成功率)
   ```
   pip index versions tensorflow
   ```

## 无效尝试

- **Upgrading pip to latest version** — The version simply doesn't exist; pip version is irrelevant. (90% 失败率)
- **Clearing pip cache with `pip cache purge`** — Cache is not the issue; the package version is absent from remote index. (85% 失败率)
