关于工程编译的问题

[leikevin]

老师好，

     使用catkin_make后，生成build目录，在build目录中执行make -j8 -l8不会进行编译。

【我的操作步骤】
mkdir catkin_ws/src -p
cd catkin_ws/src
git clone https://github.com/DroidAITech/ROS-Academy-for-Beginners-Book-Melodic.git
rosdep install --from-paths src --ignore-src --rosdistro=melodic -y
catkin_make

输出：
