编译出错鱼哥。这是为啥

[1954923637]

@2496480233 解决了吗我也是这个编译出错

[小鱼]

@1954923637 代码版本看看有没有错，最好带着上下文重新发个帖子。

@小鱼 在 提问前必看！一定要看！必须看一下！ 中说：

问题一定要描述清楚，终端打印一定复制粘贴，方便回答者检索和引用（你可以在linux系统上打开浏览器进社区）
基本的Markdown语法一定要学习下，有的小伙伴图片代码一团糟
提问时一定要提供尽可能多的信息(系统版本，ROS版本，前后操作，终端日志)，包括你的目的，比如你其实想装装某个库遇到问题，不要只说这个问题，因为可能有更好的替代方案
先搜索再提问，很多问题其实都有解决方案，确保你自己对自己的问题有一定了解再提问
尽量一句话说完，不要把社区当微信聊天一样用，每一个回复都尽量提供更多的的信息。

鱼哥，按你的教程都搞了一遍，非常赞。
但导航目前是在rviz中点击的，啥时候出一个能用代码实现的教程：
1.初次建图跟扫地机器人一样，自己走一圈建图
2.建图后，下次开机的初始定位、导航均用代码实现

[小鱼]

@154453683 nav2支持通过代码进行这些操作，可以到Nav2官方文档进行学习

[1740580485]

小鱼哥，我第一步就错了

[小鱼]

@1740580485 你的网络不行，可以试试 github代理，github.fishros.org，另外终端内容最好赋值粘贴，我好给你修改

一个好的提问不仅能够帮助自己理清楚问题，还有助于别人快速帮助到你。——提问的智慧
