# ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

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

## Root Cause

The package's setup.py fails during egg_info generation, often due to missing dependencies or syntax errors.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.8 | active | — | — |
| 3.9 | active | — | — |
| 3.10 | active | — | — |
| 3.11 | active | — | — |
| 3.12 | active | — | — |

## Workarounds

1. **Install required build dependencies manually** (85% success)
   ```
   pip install setuptools wheel && pip install mypackage
   ```
2. **Use a pre-built wheel if available** (75% success)
   ```
   pip install mypackage --only-binary :all:
   ```

## Dead Ends

- **Reinstalling the package with --no-cache-dir** — Caching is not the root cause; the setup.py itself is broken. (80% fail)
- **Installing in a different directory** — The error is inherent to the package code, not the installation path. (90% fail)
