eclipse输出信息: ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:
export ROS_MASTER_URI=http://localhost:11311
then, type ‘roscore’ in another shell to actually launch the master program
问题原因
没有添加ROS_MASTER_URI变量

在eclipse中工程build上鼠标右键点击run as,选中之前创建好的运行节点talker configuration,选中environment,点击new,输入如下图信息并点击Run.
