问题已经解决，是安装功能包时缺少了依赖，所以无法识别py文件是可执行文件，所以安装或者创建功能包时记得给出依赖：catkin_create_pkg pack_name roscpp rospy std_msgs nav_msgs；但是这里我只是下载好解压直接放进目录里面而已，并没有使用git clone。 如果还是不行，到这个网页下载中国大学慕课的ros讲义PDF：https://legacy.gitbook.com/book/sychaichangkun/ros-tutorial-icourse163/details 里面说道使用这个包时要注意安装这个包的依赖。 Linux里的包之间的依赖关系搞不懂。

遇到了同样的问题。因为git-clone网速太慢，还一直失败。直接下载的ZIP解压的。想键盘控制遇到了同样的问题。我来尝试下能不能搞好。
