# ERROR: Could not find a version that satisfies the requirement mypackage (from versions: 1.0, 1.1, 2.0) ERROR: No matching distribution found for mypackage

- **Domain:** python
- **Category:** install_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

The package versions available on the index do not support the current Python version, or the version specifier is too restrictive.

## Version Compatibility

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

## Workarounds

1. **** (90% success)
   ```
   Check the package's Python version requirement: `pip index versions mypackage` and use a compatible version.
   ```
2. **** (85% success)
   ```
   Use a virtual environment with a compatible Python version: `python3.8 -m venv venv` and install there.
   ```
3. **** (60% success)
   ```
   Look for a pre-release version: `pip install mypackage --pre`
   ```

## Dead Ends

- **** — This may install an incompatible version that crashes at runtime. (70% fail)
- **** — This is impractical and may break other dependencies. (60% fail)
- **** — The older version may also not support the current Python; the error might persist. (50% fail)
