## Root Cause

The package's setup.py/pyproject.toml raises during metadata generation, often due to missing build deps or incompatible setuptools.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

## Workarounds

1. **** (90% success)
   ```
   pip install -vvv foo
   ```
2. **** (85% success)
   ```
   pip install -U pip setuptools wheel
pip install foo
   ```

## Dead Ends

- **** — Cache is not the root cause; metadata generation still fails. (80% fail)
- **** — Pre-release may have the same broken metadata. (70% fail)
