NameError: name 'Node' is not defined

[DONJAGA]

Ubuntu: 22.04 ROS2 Humble Hawksbill Python 3.10

jupyros and dependencies installed correctly and I have provided sys path as my local ROS2 site-packages for humble as :

import sys
sys.path.append('/opt/ros/humble/lib/python3.10/site-packages/')

Then import jupyros

import jupyros

But this error kicks in as

`The rclpy package is not found in your $PYTHONPATH. Subscribe and publish are not going to work.
Do you need to activate your ros2 environment?
CvBridge not installed or sourced! Image messages will not work until then!
The rclpy package is not found in your $PYTHONPATH. Subscribe and publish are not going to work.

As my local ROS2 environment is clearly running. To make sure I even ran a ROS2 simple pub/subscript.
