[Discourse.ros.org] Ros2 topic and ros2 node command problem in MAC
I installed ROS2 on MAC and I run talker/listener application and both worked fine, but I found this warning (although it worked fine).
> Aniss-MacBook-Pro-3:~ akoubaa$ ros2 run demo_nodes_cpp listener
> Failed to load entry point 'launch': No module named 'rclpy._rclpy'
> Failed to load entry point 'echo': No module named 'rclpy._rclpy'
Here is a screenshot
Then, I tried the commands
ros2 node list
ros2 topic list
and here there was serious problem as shown in the following two pictures
