RLException: [view_hlds_laser.launch] Cannot launch the program

[AJ]

So I followed the steps as given in the documentation:

1. Installed ROS first on my Ubuntu 16.04 64-bit
2. I compiled and installed the https://github.com/ROBOTIS-GIT/hls_lfcd_lds_driver.git, as well as executed the following commands
   sudo apt-get install ros-kinetic-hls-lfcd-lds-driver
sudo chmod a+rw /dev/ttyUSB0

None of these steps had issues and ran successfully. However when I try to run
roslaunch hls_lfcd_lds_driver hlds_laser.launch
or
roslaunch hls_lfcd_lds_driver view_hlds_laser.launch
it says
RLException: [view_hlds_laser.launch] is neither a launch file in package [hls_lfcd_lds_driver] nor is [hls_lfcd_lds_driver] a launch file name The traceback for the exception was written to the log file

Not sure what's happening. Any ideas?

Thanks

If there is a problem, I recommend that you download the source code and compile it like below.

$ cd ~/catkin_ws/src
$ git clone https://github.com/ROBOTIS-GIT/hls_lfcd_lds_driver.git
$ cd ~/catkin_ws && catkin_make
$ sudo chmod a+rw /dev/ttyUSB0
$ roslaunch hls_lfcd_lds_driver view_hlds_laser.launch
