# ERROR: Package 'package' requires a different Python: 3.9.0 not in '>=3.10'

- **ID:** `python/setuptools-requires-python-mismatch`
- **Domain:** python
- **Category:** install_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The package's requires-python metadata specifies a Python version range that does not include the current interpreter.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **** (85% success)
   ```
   pip install 'package<2.0'  # version that supports Python 3.9
   ```
2. **** (90% success)
   ```
   pyenv install 3.10.0; pyenv virtualenv 3.10.0 myenv; pyenv activate myenv; pip install package
   ```

## Dead Ends

- **** — May install a package incompatible with your Python version, leading to runtime errors. (60% fail)
- **** — If the required version is a major jump, it may not be feasible or supported by other dependencies. (50% fail)
