我正在尝试在我的Raspberry Pi3（ROS Indigo）上启动ROS Master，但它却显示错误：
"ERROR: rosout is not built. Please run 'rosmake rosout'
failed to start core service [/rosout]
The traceback for the exception was written to the log file"
运行rosmake rosout后，我收到此消息：
[ rosmake ] rosmake starting...
[ rosmake ] Packages requested are: ['rosout']
[ rosmake ] Logging to directory /home/pi/.ros/rosmake/rosmake_output-20171117-153157
[ rosmake ] Expanded args ['rosout'] to:
[]
[ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['rosout']
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.
我按照wiki.ros.org的安装说明进行操作。我已经搜索过这个错误，但没有发现任何适用的错误。有没有人知道可能是什么原因？
