我正在尝试core-image-minimal使用已使用devtool build. 该工作已添加到优先级为 6 的自定义层，但我无法编译图像，因为最后遇到以下错误

这与图层优先级有关吗？我注意到meta-python提供pytest配方（5.xx）的层比我的层具有更高的优先级。如果不是有什么问题？

有两个错误：

  1. 致命的 QA 问题（因为它在ERROR_QA）。

应选择最高可用版本。行为可能会被变量 DEFAULT_PREFERENCE或变量 PREFERRED_VERSION改变。还要检查bitbake-layers其子命令的输出show-recipes，show-overlayed也许还有show-appends. 可能有一些有用的东西。

  1. 安装后挂钩失败

见行：

ERROR: core-image-minimal-1.0-r0 do_rootfs: The postinstall intercept hook 'update_gtk_icon_cache' failed, details in /home/cladm1/var-fslc-yocto/build_fb/tmp/work/imx6ul_var_dart-fslc-linux-gnueabi/core-image-minimal/1.0-r0/temp/log.do_rootfs

问题是安装后挂钩失败。Internet上有一些解决方案（或解决方法？）。还要检查提到的日志文件。

编辑：我的第一个答案是错误的，version-going-backwards被视为错误。
