# ERROR: Invalid version: '1.0.0.0.0'

- **ID:** `python/pip-install-error-invalid-version`
- **Domain:** python
- **Category:** data_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The version string does not conform to PEP 440, which allows a specific format for versions.

## Version Compatibility

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

## Workarounds

1. **** (99% success)
   ```
   pip install package==1.0.0
   ```
2. **** (90% success)
   ```
   pip index versions package
   ```
3. **** (85% success)
   ```
   Use a version like 1.0.0 or 1.0.0a1
   ```

## Dead Ends

- **** — Quoting does not fix the invalid version format. (90% fail)
- **** — Newer pip still enforces valid version syntax. (95% fail)
- **** — Force reinstall does not bypass parsing. (95% fail)
