🐛 Troubleshooting

Installation Issues

# If you get import errors
pip install --upgrade ytmcp

# If command not found
pip install --force-reinstall ytmcp

# Check installation
ytmcp --version

Common Problems

1. Video Not Found

• Verify the video ID/URL is correct

• Check if the video is public and available

• Ensure the video has captions enabled

2. Language Not Available

• Use list_available_transcripts to see available languages

• Try fallback languages like ["en", "auto"]

• Some videos only have auto-generated transcripts

3. Rate Limiting

• YouTube may temporarily block requests from your IP

• Consider using proxy configuration for high-volume usage

• Space out your requests to avoid hitting rate limits

4. Permission Errors

• Check file permissions if running on Unix systems

• Ensure Python has permission to execute the script

• Try running with appropriate user privileges
