When I installed ros2 and gazebo harmonic including stil, etc.,I installed it according to the official tutorial ROS 2 with Gazebo — Dev documentation the previous installation was normal,To the build this step colcon build --packages-up-to ardupilot_gz_bringup,It keeps prompting me that the memory is insufficient, I’ve expanded the content a lot, but it still doesn’t work, the memory expands to 40GB, and it says that the number of bytes required is much longer than my computer: here’s my error:
当我安装了 ros2 和 gazebo harmonic 包括 stil 等，我按照官方教程 ROS 2 with Gazebo — Dev documentation 进行安装，之前的安装是正常的，在构建这一步 colcon build --packages-up-to ardupilot_gz_bringup 时，它一直提示内存不足，我已经扩展了很多内容，但仍然不起作用，内存扩展到 40GB，但它说所需的字节数远远超过我的电脑：这是我的错误：~/ardu_ws$ colcon build --packages-up-to ardupilot_gz_bringup ardupilot_sitl ardupilot_gazebo ardupilot_gz_application ardupilot_gz_description ardupilot_gz_gazebo
