PermissionError when using view_frames #523

Closed roversch closed 2 years ago

roversch commented 2 years ago

I'm on ROS noetic, installed tf2_tools through apt.

I start a Gazebo simulation and simply run rosrun tf2_tools view_frames.py. I get 

[INFO] [1637331888.797080, 0.000000]: Listening to tf data during 5 seconds...

Actually, this only happens when I run it from a folder that I don't have permission to write in.

If I start from e.g. my home folder, everything works as expected.

Yeah, you need permissions to write to file in your current directory.
