hi @mnk21

Installing Python inside the container is not enough for the Code in Python node.

In n8n 2.x, this node requires a Python runner with a managed virtual environment, and that environment is missing in your setup — which is exactly what the error message indicates.

Even though python3 and pip are installed, the native Python runner is not initialized just by adding Python to the image.

Your options are:

  • Use JavaScript in the Code node (simplest)
  • Run Python via Execute Command / external service
  • Set up a supported Python runner / external runner per the n8n docs
