1.问题描述
在编译 protobuf 时遇到如下问题,总的来说就是SensorModel.cfg: Permission denied
详细错误提示如下:
/home/miracle/Project/m100/build/src/hector_gazebo/hector_gazebo_plugins/setup_custom_pythonpath.sh: 5: exec: /

2.解决方法
2.1. 查看文件权限
根据提示使用ls -al命令查看该文件权限
例如:
ls -al home/miracle/Project/m100/src/src/hector_gazebo/hector_gazebo_plugins/cfg/SensorModel.cfg2.2. 如果该文件没有x权限时,使用chmod +x命令赋予文件权限
例如:
chmod +x /home/miracle/Project/m100/src/src/hector_gazebo/hector_gazebo_plugins/cfg/SensorModel.cfg
