ROS2-Navigation2初体验:Gazebo“打不开”

输入ros2 launch nav2_bringup tb3_simulation_launch.py headless:=False后只能打开RVIZ而无法打开Gazebo的问题，多次尝试解决后发现只是多等待一会儿即可，在此给同样学习Navigation2的朋友们提个醒 。

Getting Started — Nav2 1.0.0 documentation

1.安装Navigation包

sudo apt install ros-<ros2-distro>-navigation2
sudo apt install ros-<ros2-distro>-nav2-bringup

2.安装Turtlebot 3包

sudo apt install ros-<ros2-distro>-turtlebot3-gazebo

将<ros2-distro>改为你的版本，比如我的版本是foxy，如下：

sudo apt install ros-foxy-navigation2
sudo apt install ros-foxy-nav2-bringup
sudo apt install ros-foxy-turtlebot3-gazebo

3.设置环境变量

source /opt/ros/<ros2-distr
