@linzeshi 请单独发一个帖子

我清醒着一再续杯

请这样是安装成功了吗？我之前尝试装过ros-melodic，在初始化和配置环境变量的时候出了问题。在配置环境变量的时候也是有这个“no such file or directory”的提示，然后我卸载了原来安装的ros。

在安装完ros1之后，想要测试一下，用了一下小海龟的代码出现了这个

@1924722798 没有启动roscore

我在做现实的ros小车导航，因为雷达建图不好用，我想把现有的完整图导rviz里，我已经将图片和图片附带的文件复制到map和nav文件夹下的maps了，nav下的launch文件夹下的launch文件中，内容<node name="map_server" pkg="map_server" type="map_server" args="$(find ucar_nav)/maps/mapname.yaml" output="screen">加粗字体也改好了，输入roslaunch ucar_nav ucar_navigation.launch，然后报错，该怎么办
