- **Fix Rate:** 80%

## Root Cause

The build process for the package failed because setuptools is not installed in the build environment, often due to a missing build dependency.

## Version Compatibility

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

## Workarounds

1. **** (85% success)
   ```
   pip install --upgrade setuptools wheel
   ```
2. **** (80% success)
   ```
   pip install setuptools wheel && pip install --no-build-isolation package
   ```
3. **** (75% success)
   ```
   python -m pip install --upgrade pip
   ```

## Dead Ends

- **** — May not affect isolated build environments used by pip. (60% fail)
- **** — This can work if setuptools is already installed, but often fails if it's not. (50% fail)
- **** — The missing dependency persists. (90% fail)
