the rosdep view is empty: call 'sudo rosdep init' and 'rosdep update'

修复ros录制包的时候，执行某个命令，报这个错误，报错的原因还不明白，暂时找到解决办法，参考：https://blog.csdn.net/u010918541/article/details/50445415

 

１、sudo rm /etc/ros/rosdep/sources.list.d/20-default.list

２、sudo rosdep init

３、rosdep update 此处不可以加sudo

 

因为总会报错，第三步重点是不加sudo可以解决

1	ERROR: unable to process source [https://raw.githubusercontent.com/ros/rosdistro/master/releases/fuerte.yaml]:

 

不一样的地方是增加distro了，可以看出是更新了。
