啓動運行.launch報錯[robot_launch.launch] is neither a launch file in package nor is a launch file name

完整的錯誤是：
[robot_launch.launch] is neither a launch file in package [kinova_gazebo] nor is [kinova_gazebo] a launch file name
The traceback for the exception was written to the log file
報錯說明ros系統中，並沒有安裝相對應的package。在這種情況下，進入工程文件的最頂層，使用catkin_make命令對文件進行編譯。如果此時再執行，還是會報錯的，那麼還要再加上一條語句：

source devel/setup.bash

將devel/setup.bash添加到系統，之後再運行就可以了。
