我试图在没有C编译器的树莓派系统上安装ruamel.yaml，但在安装ruamel.yaml.clib时遇到构建错误(粘贴在下面(。
我看到这是以前针对ruamel.yaml>=0.15.41, <0.16.0(如何在没有本机扩展的情况下安装ruamel.yaml(解决的问题。
请注意，在下面的输出中，path from buildroot在运行pip-install的设备上无效，而是来自生成映像的设备。

一个优选的解决方案是为ARM体系结构提供ruamel.yaml.clib轮子，或者使clib依赖性可选(pip install ruamel.yaml[clib](
我不确定为什么它在0.16之后中断，但我会试着看看为什么它再次失败(可能是setuptools现在抛出了一个不同的Exception，但没有被捕获(。
aarch64体系结构中ruamel.yaml.clib的轮子可用于piwheels。
您应该能够在添加后安装这些：

至CCD_ 9。
免责声明：我无法控制piwheels上的轮子是如何生成的。
