Answer 1

Looking at the documentation you link, turtlebot3_msgs seems to be cloned into your Catkin workspace in section 6. PC Setup - Install Dependent packages:

$ cd ~/catkin_ws/src/
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3_msgs.git
$ git clone https://github.com/ROBOTIS-GIT/turtlebot3.git
$ cd ~/catkin_ws && catkin_make

Did you do that, and was that step successful?

Can you verify that $HOME/catkin_ws/src contains a turtlebot3_msgs directory and the directory contains a ROS package?

Edit:

==>yes，I had done that( 6. PC Setup),but catkin still not successful.

==>After the step( 6. PC Setup),I check the folder turtlebot3_msgs appear in the $HOME/nick/ directory.

Packages need to be placed in the Catkin source space, not in the root of the workspace.

Please make sure the package is in $HOME/catkin_ws/src (or wherever you have the source space of your workspace located).

I search whole folder, but i can't find the two files

turtlebot3_msgsConfig.cmake turtlebot3_msgs-config.cmake

That is to be expected (ie: normal), as those are generated files which will be generated by CMake when you first invoke catkin_make. But only if the package is actually located in the source space.

Answer 2

Remove turtlebot3_msgs package from $HOME/nick/ directory and create a src folder in $HOME/nick/ and clone turtlebot3_msgs inside src folder. After this you will be able to compile.
