ROS Error: Cannot Launch Node of Type

阿新 • • 發佈：2019-01-22

問題描述:

ERROR: cannot launch node of type [ORB_SLAM/ORB_SLAM]: ORB_SLAM

原因:

This means that roslaunch cannot find the executable file ORB_SLAM anywhere in the ORB_SLAM package. Now, it's not clear to me why that's the case, but a common issue is that users do not source the setup.bash file after building which allows tools like

roslaunch to find things like this. So presumably you built the workspace containing ORB_SLAM and that would have generated this setup.bash file somewhere. But without more information on how you built or installed this package you want to use, it's hard to help you further.

原因是安裝好OPB_SLAM包後沒有source setup.bash檔案,不能把相關的環境變數,包的路徑載入進來,導致ROS不能找到對應的節點

解決辦法:

source ~/catkin_ws/devel/setup.bash

可能原因有多種，我上次遇到的原因有些記不到了。只記得一種，可能是你hadoop資料夾的許可權問題。 1、hadoop資料夾的擁有者和組不同嘗試先ll （小寫的L）檢視hadoop資料夾的擁有者和組，看是否是你當前的hadoop使用者。如果不同則修改hadoop資料夾的
