当尝试运行ROS脚本以生成无人机时，出现以下错误消息。安装了ROS Melodic，Ubuntu 18.04，一切似乎都很好...

我认为问题出在环境变量上。尝试在 ~/.bashrc 文件

中设置它们

px4_dir=~/Firmware
source /opt/ros/noetic/setup.bash
source ~/drone_ws/devel/setup.bash
source $px4_dir/Tools/setup_gazebo.bash $px4_dir $px4_dir/build/px4_sitl_default
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$px4_dir
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$px4_dir/Tools/sitl_gazebo
export GAZEBO_PLUGIN_PATH=$GAZEBO_PLUGIN_PATH:/usr/lib/x86_64-linux-gnu/gazebo-11/plugins

在ROS旋律和Ubuntu 18.04上安装MAVROS软件包
