【问题描述】：

我在构建 SDK 时收到以下冲突请求错误

我正在使用 sumo branch 和通用 core-intel-i7-64 机器配置。

运行以下命令：bitbake -c populate_sdk core-image-minimal

在最后一步失败并出现以下错误。

ERROR: core-image-minimal-1.0-r0 do_populate_sdk: Could not invoke dnf.

我在 yocto 邮件列表中发现了类似的错误，但无法理解..您能帮我解决这个问题吗..感谢您的宝贵时间

我的系统中有 /usr/bin/python

【问题讨论】：

您使用的是最新且兼容的图层版本吗？
是的..我正在使用所有版本的相扑分支

【解决方案1】：

将 RDEPENDS 添加到您的 kernel-devsrc.bb

RDEPENDS_${PN} = "bc python flex bison ${TCLIBC}-utils"
RDEPENDS_${PN} += "openssl-dev util-linux"
RDEPENDS_${PN} += "${@bb.utils.contains('ARCH', 'x86', 'elfutils', '', d)}"
