mkdir -p demo01_ws/src

lzj@lzj-VirtualBox:~$ mkdir -p demo01_ws/src
lzj@lzj-VirtualBox:~$ cd demo01_ws/
lzj@lzj-VirtualBox:~/demo01_ws$ catkin_make

进入 src 创建 ros 包并添加依赖

lzj@lzj-VirtualBox:~/demo01_ws$ cd
lzj@lzj-VirtualBox:~$ cd demo01_ws/
lzj@lzj-VirtualBox:~/demo01_ws$ cd src
lzj@lzj-VirtualBox:~/demo01_ws/src$ catkin_create_pkg helloworld roscpp rospy std_msg
