ubuntu 18.04+melodic版本ros安装问题

安装参考链接: https://blog.csdn.net/qq_32115419/article/details/81585942

(2)问题Cannot locate rosdep definition for [hector_mapping]
同样melodic里缺了这个包.
解决方法如下:
cd your_work_space/src
git clone https://github.com/tu-darmstadt-ros-pkg/hector_slam.git

(3)待以上两个都安装好以后
返回到你的workspace里,运行:
rosdep install --from-paths src --ignore-src 即可
