I'm having the same issue. Still working on it, will update if I find solution.
In 2020 it wasn't ported yet... https://answers.ros.org/question/357944/why-is-point_cloud2py-missing-from-sensor_msgs-in-ros2/ but it was supposed to have been finished that year. https://github.com/ros2/common_interfaces/pull/128
use sensor_msgs_py. The following assume Ubuntu 20/ROS2 Foxy.
download with: sudo apt-get install ros-foxy-sensor-msgs-py
in your script:
from sensor_msgs_py import point_cloud2
...
x_points = list(point_cloud2.read_points(pcl2_msg, field_names=('x')))
