ROS2 Galactic ROS-Base Install 包括哪些工具？

Question

使用哪些工具安装：

sudo apt install ros-galactic-ros-base

在官方教程（https://docs.ros.org/en/galactic/Installation/Ubuntu-Install-Debians.html，ROS-Base install）中写到安装包括：通信库，消息包，命令行工具。没有 GUI 工具。命令行工具是什么意思？

Answer 1

ROS 2 command-line工具主要指ros2cli package and common extensions. They are commonly used in the ROS 2 tutorials。以下是一些常用 command-line 工具的列表：

ros2 run用于从已安装的ROS包中执行程序。
ros2 param 允许您与节点参数进行交互。
ros2 topic 帮助您反省有关活跃 ROS 主题的信息。
ros2 launch用于执行启动文件。

要获得 ros2cli 已安装扩展的更完整列表，您可以简单地运行在终端中输入 ros2 命令，例如

$ ros2
