I use ROS fuerte before.

Now I want to use ROS groovy on the same laptop.

I found that I can run rosinstall command now, but I also can install python-rosinstall.

What's their difference?

When is the case to install python-rosinstall?

I run rosinstall:

  sam@sam:~$ rosinstall 

  usage: rosinstall [OPTIONS] INSTALL_PATH [ROSINSTALL FILES OR DIRECTORIES]
  see: http://www.ros.org/wiki/rosinstall

  Common Option:
  -n or --nobuild (don't perform a 'make core_cools' on the ros stack)

  Type 'rosinstall --help' for usage.

  Common invocations:

  initial checkout:   rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=diamondback&variant=ros-full&overlay=no"
  subsequent update:  rosinstall ~/ros


  sam@sam:~$

I run sudo apt-get install python-rosinstall

Yes,I use pip to install rosinstall. Is python-rosinstall the newer version of rosinstall? What's their difference? Thank you~

The pip installer was an approach tried, and then abandoned. Newer versions of rosinstall have not been distributed via pip for quite some time. If the old version isn't acting up, you're probably fine to continue using it, but if you use rosws or wstool (the catkin replacement), these depend on ...

python-rosinstall. And MOST IMPORTANTLY, do not install python-rosinstall without first removing the pip version -- or you'll end up with all sorts of impossible to debug errors because the new stuff is still finding parts of the old stuff...
