ROS安装问题总结

按照官网安装，遇到问题

解决方法：
pip install -U rosdep rosinstall_generator wstool rosinstall six vcstools
参考：https://blog.csdn.net/yinhuan1649/article/details/82667535?utm_source=blogxgwz8

使用 rosdep install --from-paths src --ignore-src --rosdistro=kinetic -y 安装依赖包

出现错误：
ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies:
slam_sim_demo: No definition of [hector_mapping] for OS [debian]
navigation_sim_demo: No definition of [dwa_local_planner] for OS [debian]
robot_sim_demo: No definition of [yocs_cmd_vel_mux] for OS [debian]

解决方法：
更改命令为：
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y --os=ubuntu:xenial

初始化 sudo rosdep init 报错：

ERROR: cannot download default sources list from:
https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list
Website may be down.

解决：开启代理
rosdep update 也一样
