如何解决Found the following, but the

今天在运行imu的启动程序时报错

运行：roslaunch bosch_imu_driver imu.launch

报错：ERROR: cannot launch node of type [bosch_imu_driver/bosch_imu_node.py]: can't locate node [bosch_imu_node.py] in package [bosch_imu_driver]

于是运行：rosrun bosch_imu_driver bosch_imu_node.py

报错：Found the following, but they're either not files, or not executable:

         /home/filex/catkin_ws/src/bosch_imu_driver/nodes/bosch_imu_node.py

在Google了解决办法后，发现是bosch_imu_node.py文件没有执行许可，需要运行chmod +x bosch_imu_node.py给予执行许可。运行后再执行rosrun，问题解决。
