「 Linux编译错误 rospack 」Error: package ‘ORB_SLAM2‘ depends on non-existent package ‘cv_bridge‘ and rosd

一、问题描述

        在编译ORB_SLAM2中Example的ROS时,执行到

  • $ chmod +x build_ros.sh

  • $ ./build_ros.sh

        时。报出如下错误:

[rospack] Error: package 'ORB_SLAM2' depends on non-existent package 'cv_bridge' and rosdep claims that it is not a system dependency. Check the ROS_PACKAGE_PATH or try calling 'rosdep update'

二、错误原因

        此ROS_kinetic缺少ORB_SLAM2需要的依赖包cv_bridge。

三、解决方法

        (1)通过终端安装 cv_bridge

$sudo apt-get install ros-kinetic-cv-bridge

        (2)在ORB_SLAM2文件夹中,删除之前编译好的build文件,从 ./build.sh开始向下重新编译。

#修改环境变量,在本窗口临时生效
$ export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/catkin_ws/src/ORB_SLAM2/Examples/ROS
$ cd ORB_SLAM2
$ chmod +x build.sh
$ ./build.sh
$ chmod +x build_ros.sh
$ ./build_ros.sh$ cd 
$ gedit .bashrc
#在文件末尾加上:(始终生效)
$ export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/catkin_ws/src/ORB_SLAM2/Examples/ROS

        详细的ORB_SLAM2编译过程,请看小白其它博客。
