ImportError: cannot import name 'Robot' from 'controller'

Describe the Bug
I have a problem when I want to run the executable .py on the launch. I'm currently working on ROS and when I try to run the launch it says that the library Robot cannot be imported

Traceback (most recent call last):
File "/home/user/catkin_ws/src/webots_ros/controllers/drive_1/drive_1.py", line 4, in
from controller import Robot
ImportError: cannot import name 'Robot' from 'controller' (/home/user/.local/lib/python3.8/site-packages/controller/init.py)

It looks like it loads the wrong controller library (/home/user/.local/lib/python3.8/site-packages/controller/init.py). There are two possible causes:

• Your controller Python library has been found first by Python. You will need to delete the controller package.
• Webots client library is not sourced. Check here: https://github.com/cyberbotics/webots_ros/blob/a4c93300e1528ac4f8fbf5cb7c3ecee63ff69784/launch/webots_ros_python.launch#L12-L14
