# ERROR: pip._vendor.packaging.utils.InvalidWheelName: Invalid wheel filename: mypackage-1.0.0-py3-none-any.whl (missing platform tag)

- **ID:** `python/pip-unsupported-package-format`
- **Domain:** python
- **Category:** data_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The wheel filename does not conform to PEP 427 naming convention, e.g., missing or malformed tags.

## Version Compatibility

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

## Workarounds

1. **Rename the wheel file correctly** (85% success)
   ```
   Ensure filename is like 'mypackage-1.0.0-py3-none-any.whl' (correct: mypackage-1.0.0-py3-none-any.whl is actually valid; the error is about missing platform tag, but 'any' is a valid platform. If error persists, check tags.)
   ```
2. **Rebuild the wheel with proper metadata** (95% success)
   ```
   Run: python setup.py bdist_wheel (ensures correct naming).
   ```

## Dead Ends

- **Renaming the file to remove the platform tag** — Makes the filename even more invalid. (90% fail)
- **Using a different compression format like tar.gz** — Pip expects .whl files for wheels. (80% fail)
