[FishBot教程]9.0.7. FishBot-Nav2导航测试
-
你好，小鱼，我是双系统的22.04在输入:
git clone --recursive https://github.com/fishros/fishbot.git -b v1.0.0 --depth=1
fatal: 目标路径 'fishbot' 已经存在，并且不是一个空目录。
请问怎么处理这个问题，谢谢！ -
@86181314 换个目录就行了，因为当前目录下已经存在了fishbot这一目录，也可以删掉
-
第一步出现了如下问题，不知如何解决 -
@小鱼 鱼哥，换个目录是什么意思？
-
又有新的问题 -
@921203724 别一次性运行太多指令，不然都搞不清楚是哪个出错，一步步来
看你的错误是克隆错误，已经存在fishbot工作空间了
-
@小鱼
已经下载了rosdepc，结果还是让我跑rosdep -
现在报错变了，变成这样了 -
现在变成这样了 -
-
@小鱼 可我的E盘有47.3GB可用啊

@小鱼 OSError: [Errno 28] No space left on device: 'log/build_2023-03-11_13-56-33'
鱼哥，编译告诉我空间不够了，有什么好用的办法腾出来？
-
@921203724 最好重新装下系统，分配大点空间

@小鱼 在 [FishBot教程]7. FishBot-Nav2导航测试 中说：
source install/setup.bash
ros2 launch fishbot_bringup fishbot_bringup.launch.py需要添加
cd fishbot
source install/setup.bash -
此回复已被删除！ -
鱼哥，请问一下第三部启动 bring up 报这个错如何解决？
