Troubleshooting

"spawn uv ENOENT" Error

If you see this error, it means uv is not installed or not in your PATH:

1. Install uv following the instructions above
2. Restart your terminal/Claude Desktop after installation
3. Verify installation: Run uv --version in terminal
4. Update PATH: Make sure uv is in your system PATH

Configuration Issues

• Replace /path/to/coinmarket_service with the actual path to your cloned repository
• Ensure your COINMARKET_API_KEY is valid
• The path should point to the root directory containing pyproject.toml
