下载到工作空间之后，编译会有错误。错误提示：
CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by "move_base_msgs"
with any of the following names:

move_base_msgsConfig.cmake
move_base_msgs-config.cmake

Add the installation prefix of "move_base_msgs" to CMAKE_PREFIX_PATH or set
"move_base_msgs_DIR" to a directory containing one of the above files. If
"move_base_msgs" provides a separate development package or SDK, be sure it
has been installed.
thanks

古月老师，您好，我用是Ubuntu18.04+ros melodic ，发现发布一个线速度后，小车会慢慢跑偏，请问是哪里的问题呢？
