ERROR: cannot launch node of type

[EdwinMeriaux]

Hello again,

I have another quick issue. On the running step:

roslaunch airsim_ros_pkgs airsim_node.launch;

I get:
ERROR: cannot launch node of type [airsim_ros_pkgs/airsim_node]: Cannot locate node of type [airsim_node] in package [airsim_ros_pkgs]. Make sure file exists in package path and permission is set to executable (chmod +x)

The full output is:

I apologize. But what did I do wrong?

[rajat2004]

Did you run source devel/setup.bash?

[EdwinMeriaux]

yes I did.

[rajat2004]

Maybe try doing a catkin clean, build and source again and see what happens
Also check what permissions are there, but don't think a launch file should be executable

[EdwinMeriaux]

Sorry for the confusion from where should I do catkin clean?

[rajat2004]

Same directory, all catkin commands have to be run from the ros directory

[EdwinMeriaux]

This solved the issue. Thanks!

This solved the issue. Thanks!

i meet the same problem when i run "roslaunch airsim_ros_pkgs airsim_node.launch" ,would you please to share me how you solve it ? thanks

[RobertZickler]

@NintendoLink did you check if the file is in the folder "./catkin_ws/devel/lib/"
Is your CMakeLists.txt-file correct? Does it include add_executable(<executable_file_name> <path/to/file/file.cpp)
For example: add_executable(test_file src/test_file.cpp)

I have the same problem and have several packages in my workspace does doing the catkin clean mean I have to build every package again?
