# ERROR: Package 'foo' requires a different Python: 3.8.10 not in '>=3.9'

- **ID:** `python/pip-egg-info-requires-python`
- **Domain:** python
- **Category:** install_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The package declares `requires-python = ">=3.9"` (or similar) in its metadata, and the current interpreter version is outside the allowed range.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.7 | active | — | — |
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |

## Workarounds

1. **** (90% success)
   ```
   Upgrade the interpreter to a supported version (e.g. install Python 3.11) and recreate the venv.
   ```
2. **** (80% success)
   ```
   Install an older release of the package that supports your Python: `pip install 'foo<2'` after checking `pip index versions foo`.
   ```

## Dead Ends

- **** — Installs a package that may use 3.9+ syntax and crash at import time. (50% fail)
- **** — The metadata check is independent of pip version. (80% fail)
