1、问题描述
下载了ROS-Academy-for-Beginners后，开始用rosdep安装依赖，但是发现执行官方文档提供的依赖安装命令：rosdep install --from-paths src --ignore-src --rosdistro=kinetic -y，后出现了错误，如下所示：
zzl@zzl-virtual-machine:~/prjs/rosprj/tutorial_ws$ rosdep install --from-paths src --ignore-src --rosdistro=kinetic -y
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
robot_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
navigation_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
slam_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
zzl@zzl-virtual-machine:~/prjs/rosprj/tutorial_ws$
2、解决方法：
zzl@zzl-virtual-machine:~/prjs/rosprj/tutorial_ws$ rosdep install --from-paths ./src/ROS-Academy-for-Beginners --ignore-src -r
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
robot_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
navigation_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
slam_sim_demo: Cannot locate rosdep definition for [gazebo_ros]
Continuing to install resolvable dependencies...
