CMake Error at /home/xxx/catkin_ws/devel/share/hector_mapping/cmake/hector_mappingConfig.cmake:113 (message):
Project 'hector_mapping' specifies
'/home/xxx/catkin_ws/src/hector_slam/hector_mapping/include' as an
include dir, which is not found. It does neither exist as an absolute
directory nor in
'/home/xxx/catkin_ws/src/hector_slam/hector_mapping//home/xxx/catkin_ws/src/hector_slam/hector_mapping/include'.

我到该文件夹下查看发现hector_mapping下确实没有include这个文件,Ubuntu18.04 ,ROS melodic版
请大神帮我看看，本人刚入门ROS

@gegegugu45 前置有什么操作？用的什么源码？

gegegugu45

@小鱼前置几乎没啥操作，ROS源码来源于下面这篇CSDN中的百度云盘分享，步骤也同（之前有一步骤，安装所需的依赖这部分有报错）
rosdep install --from-paths src --ignore-src --rosdistro=melodic -y会说已被占用无法获取

@小鱼刚才又尝试下载了一遍，这次貌似是镜像源的问题
rosdep install --from-paths src --ignore-src --rosdistro=melodic -y
报错如下：
E: 无法下载 http://mirrors.ustc.edu.cn/ros/ubuntu/pool/main/r/ros-melodic-yocs-cmd-vel-mux/ros-melodic-yocs-cmd-vel-mux_0.8.2-0bionic.20221025.202253_amd64.deb 无法解析域名“mirrors.ustc.edu.cn”
E: 有几个软件包无法下载，要不运行 apt-get update 或者加上 --fix-missing 的选项再试试？
ERROR: the following rosdeps failed to install
apt: command [sudo -H apt-get install -y ros-melodic-yocs-cmd-vel-mux] failed

@gegegugu45 问题有点乱哈，这三个问题之间看起来没啥关联性，应该是你哪里搞错了

针对第三个错误，可以试试用一键安装跑一遍，或者用下面指令试试

apt-get update
sudo -H apt-get install -y ros-melodic-yocs-cmd-vel-mux --fix-missing
