# 错误：'mypackage'的'console_scripts'入口点无效：'mycommand = mypackage:main'不是有效的入口点。

- **ID:** `python/setuptools-entry-points-invalid`
- **领域:** python
- **类别:** config_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

入口点字符串格式错误；必须遵循'name = module:attribute'格式，但模块或属性缺失或包含无效字符。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |

## 解决方案

1. **** (95% 成功率)
   ```
   Correct the entry point: `'mycommand = mypackage:main'` (ensure the function exists in the module).
   ```
2. **** (90% 成功率)
   ```
   Use setup.cfg with proper syntax: `[options.entry_points] console_scripts = mycommand = mypackage:main`.
   ```
3. **** (85% 成功率)
   ```
   Test the import: `python -c "from mypackage import main"` before building.
   ```

## 无效尝试

- **** — This will cause the console script not to be installed, breaking functionality. (80% 失败率)
- **** — The format requires '=' between name and target; using ':' is invalid. (90% 失败率)
- **** — Whitespace is ignored; the structure is still invalid if the target is malformed. (70% 失败率)
