Question

我完成了快速启动指南 for Foxy。一切都很顺利。

我在WSL2 Windows 11上使用Ubuntu20.04。

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS

$ printenv ROS_DISTRO
foxy

$ gazebo -version

但是，当尝试运行模拟时

$ export TURTLEBOT3_MODEL=burger
$ ros2 launch turtlebot3_gazebo empty_world.launch.py

它的消息失败了

Package 'turtlebot3_gazebo' not found: "package 'turtlebot3_gazebo' not found, searching: ['/opt/ros/foxy']"

怎么修呢？我在Reddit上找到了一个类似的线程，但没有多大帮助。

Answer 1

正如@Bilal在评论中指出的，我通过运行

sudo apt-install ros-foxy-turtlebot3-gazebo

然后，运行模拟：

set env export TURTLEBOT3_MODEL=burger
run ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py

结果：
