nav2进行导航时出现错误，求助！！

[3568485143]

根据《动手学ros2》进行fishbot的nav2导航仿真，在执行程序：
ros2 launch fishbot_navigation2 navigation2.launch.py
时终端出现以下错误：
[bt_navigator-7] [ERROR] []: Caught exception in callback for transition 10
[bt_navigator-7] [ERROR] []: Original error: Could not load library: /home/outerman1/fishbot_ws/install/nav2_behavior_tree/lib/libnav2_compute_path_to_pose_action_bt_node.so: undefined symbol: _ZTIN2BT14CoroActionNodeE
[bt_navigator-7] [WARN] []: Error occurred while doing error handling.
[bt_navigator-7] [FATAL] [bt_navigator]: Lifecycle node entered error state
[lifecycle_manager-1] [ERROR] [lifecycle_manager]: Failed to change state for node: bt_navigator
[lifecycle_manager-1] [ERROR] [lifecycle_manager]: Failed to bring up nodes: aborting bringup

rviz2中显示的内容如下：

对照github上鱼哥发的源码，发现代码部分不存在问题

当前使用的是ros2-eloquent版本，ubuntu是18.04，源码安装nav2和apt安装nav2都尝试过，均出现以上错误。

卡了好几天，希望大佬帮助一下，感谢！！
