[roslaunch] --ros-args option fails in noetic #1971
Description
Short description
Running roslaunch with the option --ros-args under ROS noetic fails.
Expected behavior
Print the arguments of the launch file like under ROS melodic.
As an example, getting the arguments of roslaunch's own example launch-file via
docker run --rm -it ros:melodic-robot roslaunch roslaunch example.launch --ros-args
gives
Optional Arguments:
commandline_true_arg (default "true"): undocumented
Acutual behavior
Running any of the below commands
docker run --rm -it ros:noetic-robot roslaunch roslaunch example.launch --ros-args
docker run --rm -it ros:noetic-robot roslaunch --ros-args roslaunch example.launch
docker run --rm -it ros:noetic-robot roslaunch /opt/ros/noetic/share/roslaunch/resources/example.launch --ros-args
docker run --rm -it ros:noetic-robot roslaunch --ros-args /opt/ros/noetic/share/roslaunch/resources/example.launch
Gives
Traceback (most recent call last):
File "/opt/ros/noetic/lib/python3/dist-packages/roslaunch/__init__.py", line 275, in main
import arg_dump as roslaunch_arg_dump
ModuleNotFoundError: No module named 'arg_dump'
Thoughts
I suspect that
should be
from . import arg_dump as roslaunch_arg_dump because of the switch to python 3.
