mkdir -p ~/test_space/src

思路： 当某一package 编译不过去的时候，可以试着把它拿出来单独编译。

in catkin_ws rm -rf build devel install ought to work as a 'superclean' that maybe would have also solved your problem. The only thing left over that could mess up your build would maybe be an old or somehow corrupted catkin_ws/src/CMakeLists.txt, rm and catkin_init_workspace to make a new one.
