Unable to launch rplidar_s2.launch

Hi,

I am working now with s2 lidar but I can't launch any launcher because I get the following error:

Checking log directory for disk usage. This may take a while.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.

I have compiled my package with catkin_make and made the sources, but I don't know why this could be happening.

Good morning again,

In case someone gets this error, it's probably due to a bad compilation of the package with catkin_make.

How did I fix this error? 1) I removed the rplidar_ros package. 2) I have removed the build folder from my ros workspace. 3) I cloned the rplidar_ros package back into my src folder 4) I recompiled the workspace with catkin_make
