I am trying to get the turtlebot Project (Simulator) running on my system, but I do not get it to run.
I have done the following steps:
**1) Create a own workspace with**
$mkdir -p ~/turtlebot_ws/src
**2) Run catkin_make in ~/turtlebot_ws/**
get the folder
**3) Add the following line into my ./bashrc**
// needed to get gazepo run in VMware
echo export SVGA_VGPU10=0
// needed for the base installation of ROS
echo source /opt/ros/kinetic/setup.bash
echo open ".bashrc" to modify the active ROS project
// for the beginner project needed
// for the Turtlebot project needed
**4) Check the ROS variables and get the following result**
$ printenv | grep ROS
**5) get the turtlebot project from git**
$~/turtlebot_ws$ git clone https://github.com/turtlebot/turtlebot.git
**6) Try to run the simulation**
$~/turtlebot_ws$roslaunch turtlebot_gazebo turtlebot_world.launch
get the follwoing error message
[turtlebot_world.launch] is neither a launch file in package [turtlebot_gazebo] nor is [turtlebot_gazebo] a launch file name
The traceback for the exception was written to the log file
**7) Run the Check installation tool "roswtf"**
an get the following result:

Can somebody help me to fix this. Maybe I have forgot something.
I have to admit, I am new in ROS, but I have already read and execute the beginner_tutorials,
which has worked fine for me.
