我正在运行Kubuntu 12.04.4 LTS和ROS Hydro。
尝试完成MoveIt时！这里的“设置助手教程”
http://docs.ros.org/hydro/api/moveit_setup_assistant/html/doc/tutorial.html
一切正常，直到我尝试第4步。当我点击“添加组”按钮时，MoveIt！ Setup Assistant GUI关闭，我收到以下错误：
/opt/ros/hydro/lib/moveit_setup_assistant/moveit_setup_assistant: symbol lookup error: /opt/ros/hydro/lib/libmoveit_setup_assistant_widgets.so: undefined symbol: _ZN3ros7package10getPluginsERKSsS2_RSt6vectorISsSaISsEEb
