Expected behavior

rclpy successfully imported.

Actual behavior

Import failure.

Additional information

I’m not sure what’s causing this issue. A ROS 2 scripts on my machine that worked before suddenly stopped working, and it turned out to be a import failure. Also, the trobleshooting guide in the error message seems to be only for Windows. Thank you.
