RLException: Unable to contact my own server at [http://192.168.31.213:44895/].

描述：本来有一个foxy版本ROS，后来又一键安装了一个noetic的版本，然后在网上搜索后把foxy版本的删除了，现在又通过一键安装下载回来了现在每次打开终端之后，会先有这个询问：ros:foxy(1) noetic(2) ?
我输入 2 换行后，输入roscore，出现上述问题。

[fxdzz]

大佬，这是什么情况

@小鱼 请问运行ros2 doctor后输出
/opt/ros/humble/lib/python3.10/site-packages/ros2doctor/api/init.py: 118: UserWarning: Fail to call PackageCheck class functions.

All 4 checks passed
这是怎么回事，运行ros2 run demo_nodes_cpp talker
ros2 run demo_nodes_cpp listener
后可以收到消息

能问下图中的ModuleNotFoundError: No module named 'robot_vision_msgs'是什么问题
