ROS 编写第一个程序 hello world遇到的问题

创建的工作空间一定要在英文目录下，不然怎样改程序都不会运行

 

 编译通过后报错：

terminate called after throwing an instance of 'ros::InvalidNameException'
what(): Character [ ] is not valid as the first character in Graph Resource Name [ hello _ros ]. Valid characters are a-z, A-Z, / and in some cases ~.

源文件cpp的问题，检查自己代码是否正常，cpp文件名是否正确

 

编译成功后记得设置环境变量，即 source devel/setup.bash
