@2425004936 在 在编译navigation2及其依赖的时候，产生- The generic dependency on 'nav2_bringup' is redundant with: exec_depend错误，一直无法解决 中说：

exec_depend

检查下对应的 packages.xml ，另外给出上下文

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

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。

@小鱼 好的，谢谢你

@小鱼 解决了nav2_bringup错误。确实是packages.xml写错了。目前编译nav2包及其依赖项时一直提示"1 package failed: nav2_mppi_controller
"系统是ubuntu22.04，humble版本。我源码下载的是humble版本。

如下是错误信息：

@2425004936 又一个出现这个问题的。

[小鱼]

@1367426346 我来check下

这样操作

git clone https://github.com/ros-planning/navigation2.git -b humble
git reset 1.1.9

回退下版本后测试

@小鱼 在 在编译navigation2及其依赖的时候，产生- The generic dependency on 'nav2_bringup' is redundant with: exec_depend错误，一直无法解决 中说：

git reset 1.1.9

试了一下，回退版本还是无法编译成功。错误提示还是和上面一样

[2693226252]

@2425004936 你好，你怎么改的package.xml文件啊

[1548792408]

我在编译的时候也遇到了同样的问题，求解答。

对应教程地址：
https://fishros.com/d2lros2/#/humble/chapt11/get_started/3.使用FishBot进行自主导航

具体错误：

colcon build --packages-up-to fishbot_navigation2

[1548792408]

@1548792408 补充：

1. 下载 nav2 时采用的是源码方式（依赖也按照教程用rosdepc install -r --from-paths src --ignore-src --rosdistro $ROS_DISTRO -y下载了）
2. 并且在终端也将 nav2 source到工作空间了

[1548792408]

@1548792408
已解决！
不知道什么原因，如果只用下面这条语句，在源码编译的时候没有编译 包nav2_bringup

colcon build --packages-up-to navigation2

至于我是怎么发现没有编译 包nav2_bringup的：在工作空间目录（即fishbot_ws）下的 install 文件夹中你会发现没有 包nav2_bringup 对应的文件夹。

我采用的解决方法（单独对缺失的 包nav2_bringup 进行编译）:

cd fishbot_ws
colcon build --packages-up-to nav2_bringup
