When following the tf tutorial,there are errors here: After typing "roslaunch turtle_tf_broadcaster start_demo.launch", it returns "ERROR: cannot launch node of type [learning_tf/turtle_tf_broadcaster]: can't locate node [turtle_tf_broadcaster] in package [learning_tf]" How can I correct it?

I built with catkin and had the same problem. I solved it by executing the command "source devel/setup.sh" in the catkin workplace before running the launch file. (I always forget to run it....)

Make sure you have included all the package that are needed within your CmakeList.txt. For instance, I forget to included rospy and it didn't work for me. And if that didn't work try deleting the build and devel folders within you package and recompile it with catkin_make.

Might not work, until you do catkin_make within your workspace

The executable either isn't there or isn't named "turtle_tf_broadcaster". Make sure you run catkin_make and check your CMakeLists.txt to see what the executable is named.
