动手4.3.2报错

@小鱼 不行。还是同样的报错。难道是我用的ubuntu18.04配置的ros2-eloquent这个版本和教程不一样？我看那个一键安装的ros2的脚本就只有到eloquent这个版本

@505106035 版本问题有很大可能，你用的版本已经停止维护有一段时间了。
-
@505106035 ubuntu18上没有foxy版本，只有ubuntu20才支持
-
@小鱼 我用win电脑装了个vm配置了u20。装的ros2-rolling就好使。醉了
-
@505106035 ROS2前几个版本更新的很快，所以差异比较大

@小鱼 鱼哥，我的系统版本是22.04.3，ROS版本是humble，和上面的问题有点类似，但感觉不太一样，应该怎么解决？？

@751365166 尽量避免路径中出现中文，这会产生很多未定义行为。（ROS开发者可不会想到你会输入除英文以外的路径哈哈

@ganyuanzhen 我懂了！！！感谢，问题出在，我应该新建一个英文名称的文件夹，然后在新建文件中运行终端命令！而不应该直接在桌面运行终端。
