Python 使用yocto为Raspberry pi 3生成图像时分析错误

我试图通过引用使用yocto为Raspberry pi 3构建图像，在运行bitbake命令时，我遇到以下错误

在错误日志中，它在执行python函数时显示error，但没有关于错误的详细信息，我可以看到异常“exception:TypeError:getVar（）至少接受3个参数（给定2个）”。但在yocto的许多地方，我可以看到getVar只接受了两个参数

你能指导解决这个问题吗。我可以在很多地方看到d.getVar（），你能告诉我这里的d是什么吗？我在yocto文档中搜索了一下，但没有找到任何解释d是什么的信息
