# error: Invalid entry point 'console_scripts' for 'mypackage': 'mycommand = mypackage:main' is not a valid entry point.

- **ID:** `python/setuptools-entry-points-invalid`
- **Domain:** python
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The entry point string is malformed; it must follow the format 'name = module:attribute', but the module or attribute is missing or has invalid characters.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |
| 3.11 | active | — | — |

## Workarounds

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

## Dead Ends

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