使用rosmake编译ROS功能包时出错：“IOError: [Errno 13] Permission denied: '/home/xxx/.ros/rosdep/sources.cache/”
自己在Ubuntu下搭了一个ROS的开发环境，使用rosmake时提示出错：
true@ubuntu:~/dev/rosbook$ rosmake chapter2_tutorials

一开始以为环境变量有问题查看了
true@ubuntu:~/dev/rosbook$ cat ~/.bashrc
source /opt/ros/indigo/setup.bash
export ROS_PACKAGE_PATH=~/dev/rosbook:/opt/ros/indigo/share:/opt/ros/indigo/stacks显示正常
后来使用如下方式解决：
true@ubuntu:~/dev/rosbook$ sudo rm -fr /home/true/.ros/rosdep/sources.cache
true@ubuntu:~/dev/rosbook$ rosdep update
