When I run the roslaunch command, an RLException error occurs
The text is the same as the title. I tried various methods on google to solve this error. But it doesn't work, so I need your help. Anyone is welcome, please help me to solve this error.
awesometech@awesometech:~/catkin_ws$ roslaunch urs_wearable world.launch

Arg xml is The traceback for the exception was written to the log file
this is my code I think there is no error in this code.
<?xml version="1.0"?>
<launch>
<include file="$(find urs_wearable)/launch/world.launch">
<arg name="world" value="$(find urs_wearable)/worlds/test.world" />
<arg name="reference_latitude" value="32.319939" />
<arg name="reference_longitude" value="-106.763657" />

You appear to be roslaunch-ing a file called world.launch, which is hosted by a package called urs_wearable.
That file includes a file called world.launch, which is also located in the package urs_wearable (ie: the same package).
From the traceback, it's clear this leads to the situation where roslaunch is trying to load the file world.launch, which tries to include the file world.launch, which tries to include the file world.launch, which tries to include the file world.launch, which tries to include the file world.launch, which tries to include the file world.launch, etc, ad infinitum -- or in this case, until the Python interpreter reaches an internal limit and "just gives up".
Summarising: you need to prevent the infinite recursion.
Could you clarify why you include the same file you are already trying to roslaunch? If you avoid that, I believe you'd avoid the problem you encounter.
