can not find local path of re_comm package (error in environmental variable ROS_ROOT ) [closed]

edit

Hi :D,

I try to download a recipe from RoboEarth, but system does not find path to re_comm package !! I do not understand what is the error related to ?!

I run this in a terminal roslaunch re_comm re_comm_knowrob.launch

and this in other one

rosrun rosprolog rosprolog re_comm

then visualisation_canvas(_), planvis_create(_).

then re_download_action_recipe('serve a drink', pr2:'PR2Robot1', Recipe), re_generate_cpl_plan(Recipe, CplPlan),planvis_load(Recipe,_).
