运行报错

[Ayipan]

你好，在环境搭建好后，运行roslaunch scope_nav dwa_so_scope_pu_nav.launch时，出现报错RLException: [dwa_so_scope_pu_nav.launch] is neither a launch file in package [scope_nav] nor is [scope_nav] a launch file name；The traceback for the exception was written to the log file。
我尝试在pc和container两种方式去运行，都是得到这个结果。

Please ensure that the ROS workspace has been compiled and the setup is loaded in the terminal, as shown below:

catkin_make
source ~/catkin_ws/devel/setup.sh

I'm sure it's already running ROS workforce and the setup has been loaded in the terminal,the attachment contains my operation log, you can check it,thank you.

It appears your system is using a different shell, please try to use setup.bash as following to fix your issue:

catkin_make
source ~/catkin_ws/devel/setup.bash

[Ayipan]

I tried your method, but got the same error result,and I have successfully running drl_vo_nav on a singularity container.

Please provide your system environment version, as I tested it on my Ubuntu 20.04 system and did not encounter this problem. You can run the below commands with *.zsh to test:

cd ~/catkin_ws
catkin_make
source ~/catkin_ws/devel/setup.zsh
rospack find scope_nav
roslaunch scope_nav dwa_so_scope_pu_nav.launch

In addition, ensure that the scope_nav package is located in the catkin_ws space, and test whether the launch files of other packages can also be found in your catkin_ws space.

Figure 1 shows my system environment,I also test it on my ubuntu 20.04 system.I tried command with *.zsh,but it shows command not found,while scope_nav also can't be found,but I check my catkin_ws documents,it does have scope_nav,and it can be check in figure 2.

[zzuxzt]

Captured your bug: please place the scope_nav package in the ~/catkin_ws/src/ folder!

Refer to install ros packages in ReadMe.

[Ayipan]

I place the scope_nav package in the ~/catkin_ws/src/ folder,but it seems that a new error has occured,saying that some file names are overlapping.

I changed the name of goal_visualize node to goal_visualize_scope as dwa_so_scope_pu_nav.launch. You can change it by yourself or git update the new code.
