我创建了一个名为catkin_ws的工作区。然后，catkin_make运行成功。之后，我键入catkin_create_pkg ros_basics_tutorials std_msgs rospy roscpp，然后键入在ros_basics_tutorials文件夹中创建的所有文件夹和文件。
但是，在该命令之后，我键入cd catkin_ws
然后catkin_make
以下错误显示为Cmake错误，找不到cpp(缺少：cpp_DIR(，Cmake_check_build_system'失败

我解决不了？如何解决？
错误是由于我在catkin_ws下取消的anathor项目文件夹。我删除了它，然后又照办了。错误已解决。
