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

RLException: Unable to contact my own server at [http://192.168.31.213:44895/].
This usually means that the network is not configured properly.

A common cause is that the machine cannot connect to itself. Please check
for errors by running:

ping 192.168.31.213

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。
