使用yocto为Raspberry pi 3构建图像时解析错误

标签： python linux raspberry-pi yocto

我正在尝试使用yocto通过引用this为Raspberry pi 3构建映像，而运行bitbake命令时出现以下错误。

在错误日志中，它在执行python函数时显示错误，但没有关于错误的详细信息，我可以看到异常＆＃34;异常：TypeError：getVar（）至少需要3个参数（2给出）＆＃34; 即可。但是在yocto很多地方我都能看到getVar只有两个参数。

您可以指导解决此问题吗？我可以看到d.getVar（）很多地方，你能告诉我这里有什么，我在yocto文档中搜索但是没有找到解释什么是d的信息。

我遇到了同样的问题，并通过切换到 meta-raspberrypi 层上的 morty 分支来修复，这与我的poky环境的分支相同。
