CMake Error at /opt/ros/melodic/share/catkin/cmake/catkin_package.cmake:116 (message):catkin_package

前几天看ROS教程（三）：创建程序包及节点（图文），想用ROS创建节点进行交互，结果catkin_make编译到80%的时候报错，CMake Error at /opt/ros/melodic/share/catkin/cmake/catkin_package.cmake:116 (message):catkin_package() ‘catkin’ must be listed as a buildtool dependency in the package.xml，后面终于解决了。
首先

cd ~/catkin_ws/src
sudo gedit package.xml

修改packge.xml文件，在roscpp前面加上catkin

catkin

保存退出，再

cd ~/catkin_ws
catkin_make

就编译成功了
