【英文标题】："ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py" results in package not found

【问题描述】：

这些是使用的命令：

$ source /opt/ros/foxy/setup.bash
ROS_DISTRO was set to 'noetic' before. Please make sure that the environment does not mix paths from different distributions.
$ export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:~/turtlebot3_ws/src/turtlebot3_simulations/turtlebot3_gazebo/models
$ export TURTLEBOT3_MODEL=burger
$ ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py
Package 'turtlebot3_gazebo' not found: "package 'turtlebot3_gazebo' not found, searching: ['/opt/ros/foxy']"

【参考方案1】：

路径中是否可能缺少子目录？

export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:~/turtlebot3_ws/src/turtlebot3/turtlebot3_simulations/turtlebot3_gazebo/models

或者，如果您不需要工作区，您可以使用以下内容：

export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:/opt/ros/foxy/share/turtlebot3_gazebo/models
