在Windows设备上使用二进制文件安装Ros2,并在尝试页面上的第一个tutorials时遵循Ros installation guide。当尝试使用以下命令构建包时,我得到以下错误。

colcon build --merge-install

--- stderr: test1

我可以在包含pkg_resources的pip列表中看到setuptools 65.6.3。
我已经在另一台计算机上测试过,并从Ros 2文档的其他例子,我得到相同的错误每一次。错误是相同的问题讨论here。然而,提供的两个链接最终都是徒劳的。任何洞察问题是什么,以及如何解决它将是有帮助的。
编辑:这里是CMakeList.txt文件,似乎是问题所在

好吧,所以解决方案是通过微软IOT的ROS2 windows setup安装ROS2。可悲的是,我不知道问题是什么开始,但这是一个体面的变通办法,任何人有问题安装ROS 2 foxy fitzroy在windows上。
