RLException: multiple files named [] in package [] when doing roslaunch

roslaunch RLException

Windows do not really distinguish the uppercase and the lowercase for the name of a folder.

And the above error happened because I entered the same file with different capitalized words.

e.g.

• RETINA_Analyzer_ROS
• retina_analyzer_ros
• ReTiNa_AnAlYzEr_RoS

So I had to figure out a way do delete the other two paths, but I could not figure out.

 

So the alternative way was that I get into the launch file to do roslaunch.

You can use the following command: in ...catkin_ws/src/(project name)/launch$

roslaunch -v run.launch

 

Then the file succesfuly ran without multiple path errors.
