source ~/.bashrc之后,里面的source /opt/ros/kinetic/setup.bash会被调用,其作用之一就是将/opt/ros/kinetic/share加入到ROS_PACKAGE_PATH里面去。所以每次我们开启一个终端,输入roscore或是rosrun 系列自带的package,都可用正常启动,而不会报错说找不到package(如果没写进bashrc里面就会报这个错),就是这个原因:...
如果在创建ROS工作空间时不是严格按照如下命令来创建 $ mkdir -p ~/catkin_ws/src 来创建的话可能后面会出现找不到包的情况,这个时候你用命令 $ echo $ROS_PACKAGE_PATH 会发现所找不到的包没有包含在这个路径里面,这个时候你可以人为地去添加路径到ROS_PAKAGE_PATH路径中 方法如下: 1、打开终端脚本～/.ba...
如果你的所有程序都链接到某个自定义的查找路径指定的动态库文件,若某次执行程序前你忘记了设置LD_LIBRARY_PATH环境变量,这样你的程序会链接到其他动态库,可能会导致诡异的结果或意外崩溃,而且在可能存在潜在的安全问题。 如果不考虑上述的各种情况,你可以通过修改home目录下的 .bashrc 文件来设置LD_LIBRARY_PATH环境...
unsetROS_PACKAGE_PATH 把所有的路径清除，然后把.bashrc文件里和该工作空间有关的语句注释掉，比如source...
跟 source 不 source 没有关系。相反的，正是在 source 的过程中，bash工具才需要setup.bash这个文件，...

Short version: I broke my ROS_PACKAGE_PATH, and now I don't know how to get my workspace to work again. I'm using rosbuild, not catkin, and jade; on ubuntu. Long version: I'm pretty much completely new to ros, and I have been working on an existing project from a coworker....
export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/ws_temp/BagFromImages cmake .. make When using the code, remember to run the following command again: export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:~/ws_temp/BagFromImages alternatively you can permanently add it to the.bashrc. ...
colcon-ros maintains ROS_PACKAGE_PATH for ROS1/catkin packages, but not for ROS2 packages. Without this, ROS2 users of rosdep must maintain ROS_PACKAGE_PATH by hand. See: https://answers.ros.org/question/315296/crystal-rosdep-cannot-find-all-required-resources/...
