By not providing "Findlaunch_testing_ament_cmake.cmake" in

not find one.

Could not find a package configuration file provided by

Add the installation prefix of "launch_testing_ament_cmake" to

containing one of the above files. If "launch_testing_ament_cmake"
provides a separate development package or SDK, be sure it has been
installed.

@3508827352 手动安装下 sudo apt install ros-你的ROS版本代号-launch-testing-ament-cmake

[小鱼]

@3508827352 另外注意格式

@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
