source /opt/ros/melodic/setup.bash

在创建了ROS的workspace后，需要将workspace中的setup.bash文件写入~/.bashrc 文件中，让其启动。你可以在终端中使用以下命令将source /opt/ros/melodic/setup.bash添加到.bashrc文件中：

echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc

这样，在每次打开终端时，ROS的环境变量就会被自动设置。 这个命令将会在.bashrc文件的末尾追加这个source命令，以确保ROS环境变量在每次启动终端时都能生效。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
