OSError: [Errno 13] Permission denied: '/home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/default_warehouse_mongo_db'

HI all! I'm trying create a moveit package for my own robot following the tutorial Create_a_MoveIt_Pkg_for_an_Industrial_Robot. When I finished the second part Update Configuration Files I tested the configuation.However, there was something wrong. When I start the planning _and_execution.launch, there was something output like this: OSError: [Errno 13] Permission denied: '/home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/default_warehouse_mongo_db' [mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7] process has died [pid 9194, exit code 1, cmd /opt/ros/indigo/lib/warehouse_ros/mongo_wrapper_ros.py __name:=mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499 __log:=/home/shantengfei/.ros/log/e378d02c-b477-11e7-9896-7085c22fcebd/mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7.log]. log file: /home/shantengfei/.ros/log/e378d02c-b477-11e7-9896-7085c22fcebd/mongo_wrapper_ros_shantengfei_PC_9122_1384786663048058499-7*.log I checked the ros package **jaka_ur_moveit_config** and there are just two folders: **launch** and **config**. In the **launch** folder, there is a **default_warehouse_db.launch** file which was generated when I set up the moveit assistant: and here is the moveit_planning_execution.launch As can be seen, ``. But I didn't find the `default_warehouse_mongo_db`.Could someone please give a method to solve the problem? Thanks. PS: Here is the output of ` ls -al /home/shantengfei/catkin_ws/src/jaka_ur_moveit_config` drwxr-xr-x 4 root root 4096 10月 16 10:00 . drwxrwxr-x 8 shantengfei shantengfei 4096 10月 18 22:51 .. -rw-r--r-- 1 root root 310 10月 16 10:00 CMakeLists.txt drwxr-xr-x 2 root root 4096 10月 23 15:33 config drwxr-xr-x 2 root root 4096 10月 17 16:32 launch -rw-r--r-- 1 root root 1069 10月 16 10:00 package.xml -rw-r--r-- 1 root root 284 10月 16 10:00 .setup_assistant and the output of `ls -al /home/shantengfei/catkin_ws/src/jaka_ur_moveit_config/launch`: drwxr-xr-x 2 root root 4096 10月 17 16:32 . drwxr-xr-x 4 root root 4096 10月 16 10:00 .. -rwxrwxrwx 1 root root 715 10月 16 10:00 default_warehouse_db.launch -rw-r--r-- 1 root root 2521 10月 16 10:00 demo.launch -rw-r--r-- 1 root root 370 10月 16 10:00 fake_moveit_controller_manager.launch.xml -rw-r--r-- 1 root root 299 10月 17 16:32 jakaUr_moveit_controller_manager.launch.xml -rw-r--r-- 1 root root 20 10月 16 10:00 jakaUr_moveit_sensor_manager.launch.xml -rw-r--r-- 1 root root 629 10月 16 10:00 joystick_control.launch -rw-r--r-- 1 root root 3418 10月 16 10:00 move_group.launch -rw-r--r-- 1 root root 1051 10月 17 15:07 moveit_planning_execution.launch -rw-r--r-- 1 root root 968 10月 17 15:05 moveit_planning_execution.launch~ -rw-r--r-- 1 root root 19020 10月 16 10:00 moveit.rviz -rw-r--r-- 1 root root 672 10月 16 10:00 moveit_rviz.launch -rw-r--r-- 1 root root 966 10月 16 10:00 ompl_planning_pipeline.launch.xml -rw-r--r-- 1 root root 1208 10月 16 10:00 planning_context.launch -rw-r--r-- 1 root root 335 10月 16 10:00 planning_pipeline.launch.xml -rw-r--r-- 1 root root 910 10月 16 10:00 run_benchmark_ompl.launch -rw-r--r-- 1 root root 647 10月 16 10:00 sensor_manager.launch.xml -rw-r--r-- 1 root root 540 10月 16 10:00 setup_assistant.launch -rw-r--r-- 1 root root 1329 10月 16 10:00 trajectory_execution.launch.xml -rw-r--r-- 1 root root 523 10月 16 10:00 warehouse.launch -rw-r--r-- 1 root root 592 10月 16 10:00 warehouse_settings.launch.xml
