Error calling tool claude_code_async: Command failed with exit code 127 (exit code: 127) Error output: Check stderr output for details

My backend is built with FastAPI and uses claude-agent-sdk-python to control Claude code. After packaging, it returns:
Error calling tool claude_code_async: Command failed with exit code 127 (exit code: 127) Error output: Check stderr output for details

How can I dynamically set the path to Claude code? After packaging, I may need to dynamically pass the Claude code path to claude-agent-sdk-python to avoid exit code 127.

It doesn't seem to be an issue with this SDK. The problem occurs when I repackage it with Electron, causing the Claude code to be missing. If I only package the backend with PyInstaller, it can be found. The error probably isn't in this project.
