如果需要更换源，最后别忘了下面命令更新一下

sudo apt-get update

执行命令安装ros

wget http://fishros.com/install -O fishros && . fishros

终端输入上面命令进行安装ros，会自动帮我们检测环境依赖

RUN Choose Task:[请输入括号内的数字]
如果您是第一次安装，推荐您先更换一下系统源
[1]:更换系统源再继续安装
[2]:不更换继续安装
[0]:quit
请输入[]内的数字以选择:2

因为我的源已经更换过，所以选择2

[1]:melodic
[2]:bouncy
[3]:crystal
[4]:dashing
[5]:eloquent
[0]:quit
请输入[]内的数字以选择:1

ubuntu版本对应安装ros版本如下：

请选择安装的具体版本:
[1]:melodic完全版
[2]:melodic基础版(小)
[0]:quit
请输入[]内的数字以选择:

这里我选择的是1，安装完全版，然后回车就进入安装的过程了
安装完后我们还需要初始化一下rosdep，这里继续用大佬的源

然后回车，配置好后会有如下提示

已为您安装好rosdepc,请使用:
rosdepc update 
进行测试更新,最后欢迎关注微信公众号《鱼香ROS》
一键安装已开源，欢迎给个star/提出问题/帮助完善：https://github.com/fishros/install/ 

我们执行命令更新一下

rosdepc update

至此，ros的安装就完成了

环境配置

环境配置我们最好根据官网教程自己手动配置一下,大佬的工具也是把ros安装在opt目录下

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

现在我们验证一下，打开三个终端，分别执行以下命令

roscore
rosrun turtlesim turtlesim_node
rosrun turtlesim turtle_teleop_key

如下图所示，说明ros安装成功

如果你觉得启动三个终端太麻烦，也可以写一个启动的脚本 turtlesim.launch

<launch>
    <node pkg="turtlesim" name="turtle1" type="turtlesim_node"/>
    <node pkg="turtlesim" name="turtle1_key" type="turtle_teleop_key"/>
</launch>

这样我们就可以直接在终端执行命令启动

roslaunch  turtlesim.launch

最后再膜拜一下鱼香ros大佬，这个工具太好用了
