win_ros roslaunch error can't find module
I am trying to get win_ros running and am having problems (I plan to have some nodes running on a Windows machine due to some hardware only having Windows support, with the main ROS system on Linux).
I followed the instructions on: win_ros hydro Msvc SDK
Installing all the python packages, and extracting the precompiled SDK and rosdeps to C:\opt, and adding to my path variable.
Right now I'm trying to test the system before attempting any of my own development following the test instructions: I call C:\opt\ros\hydro\x86\setup.bat, and as a test I ran rospack list and all the expected packages show up in the list. However, when I try to run roscore I get: ImportError: No module named roslaunch Is there something I have missed in the setup? Is there other scripts I need to run besides C:\opt\ros\hydro\x86\setup.bat
I tried to reproduce your situation on clean pc installed Windows 7, but couldn't reproduce it. Check PYTHONPATH after call c:/opt/ros/hydro/x86/setup.bat like 'echo %PYTHONPATH%' on Windows command prompt, and check you can import roslaunch via command line of python client.
