IOError: [Errno 1] Operation not permitted

Wintho,

Do you see the same error if you log in as a root?

Cannot initialize/control PWM when running ROS node (permission denied)

Hi, @djsuo You can’t use sudo as your environment variables aren’t set for user root, therefore it’s impossible to run rosrun. You can login as root and source setup.bash. Then everything should work.
