Make sure you have a supported version of Pythoninstalled on your system, which should be one ofthese: ${SUPPORTED_VERSIONS.map((e) => `${e[0]}.${e[1]}`).join(", ")}
If the module still somehow fails to find it,you can open an issue: https://github.com/denosaurs/deno_python/issues
However, if your Python distribution is not in searchpath, you can set DENO_PYTHON_PATH env variable pointingto dll/dylib/so file for Python library.`);
