## 解决方案

   mkdir -p mypackage/data && touch mypackage/data/config.yaml
   ```
2. **Correct the package_data glob pattern** (85% 成功率)
   ```
   In setup.cfg: 'include = mypackage/data/*.yaml' and ensure files are present.
   ```

## 无效尝试

- **Creating an empty file with the same name** — The file may need specific content; an empty file may cause runtime errors. (70% 失败率)
- **Removing the package_data entry** — This may break functionality that depends on the file. (60% 失败率)
