## Workarounds

1. **Ensure correct URL and credentials** (90% success)
   ```
   pip install git+https://user:token@github.com/user/repo.git
   ```
2. **Clone manually and install** (80% success)
   ```
   git clone https://github.com/user/repo.git && cd repo && pip install .
   ```

## Dead Ends

- **Using HTTPS instead of SSH** — May still have auth issues. (50% fail)
- **Checking if git is installed** — Git is usually present. (20% fail)
