You need to have roslaunch
in your ROS_PACKAGE_PATH
so that it can be found. rosversion
does not work with rosdistro
, it works locally. So, if it cannot find the package locally then it will fail like that:
% rosversion roslaunch
Cannot locate [roslaunch]
% groovy # alias to source ~/groovy/ros_catkin_ws/install_isolated/setup.zsh
% rosversion roslaunch
1.9.41

EDIT:
The problem is that you have most likely unset or otherwise changed your ROS_PACKAGE_PATH
such that roscore
is on the PATH
and roslaunch
is on the PYTHON_PATH
, but roslaunch
is not on the ROS_PACKAGE_PATH
.

EDIT:
Also make sure that rospkg
is not installed via pip, an older version in pip might be overriding the version of rospkg
which is getting used. You can double check the version like this:
python
>>> import rospkg
>>> rospkg.__version__
0.1.19
>>> rospkg.__file__
/some/path/which/should/be/under/usr/not/usr/local
And:
which rosversion
Should return somewher in /usr/
not /usr/local/
.
