      @2418760838 你补充一下你目前的bashrc(复制粘贴代码快包括),和source之后的错误提示

              ROS_DISTRO was set to 'foxy' before. Please make sure that the environment does not mix paths from different distributions.

                  @2418760838 打开心终端会提示ros:foxy(1) noetic(2) ?吗?

                  这个符号看起来很奇怪

                  1) source  /opt/ros/foxytup.bash;;
                  2) source  /opt/ros^etictup.bash;;
