Error in gazebo in ROS Melodic
Hi Everyone,
I am following a tutorial for gazebo in http://wiki.ros.org/simulator_gazebo/... and http://wiki.ros.org/simulator_gazebo/...
I am using ros melodic, and my ubuntu version is 17.10
My problem is: when I type in
sudo apt-get install ros-melodic-simulator-gazebo
it shows:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package ros-melodic-simulator-gazebo
But if I type in
sudo apt-get install ros-melodic-simulators
Seemingly it works out, but there is a Note says that the second line of code works for indogo version.
Moreover, I cannot use
roslaunch gazebo_worlds empty_world.launch
to launch gazebo, and it would give me like this: RLException: [empty_world.launch] is neither a launch file in package [gazebo_worlds] nor is [gazebo_worlds] a launch file name The traceback for the exception was written to the log file
I can only use
roslaunch gazebo_ros empty_world.launch
instead. It directly causes the biggest problem: When I launch gazebo, and try to follow the guide for Simple Box URDF as I type in
rosrun gazebo spawn_model -file pwd/object.urdf -urdf -z 1 -model my_object
It says [rospack] Error: package 'gazebo' not found
Can someone help me out? Great thanks in advance!
