【问题描述】：
我正在尝试为包含 Qt5 的 beaglebone 构建映像，并为此映像生成 SDK。
问题
我的问题是，构建失败了 do_populate_sdk 任务来创建 SDK 并出现以下错误：
错误：事务检查错误： 文件 /opt/poky/2.3.1/sysroots/x86_64-pokysdk-linux/environment-setup.d 尝试安装 nativesdk-cmake-3.7.2-r0.x86_64_nativesdk 和 nativesdk-qtbase-tools-5.8.0+ 之间的冲突git0+49dc9aa409-r0.x86_64_nativesdk
再往上游一点，我遇到了以下错误消息：
错误：无法调用 dnf。命令'/home/ubuntu/workspace/bbb/build-toaster-2/tmp/work/my_machine-poky-linux-gnueabi/my-image-dev/1.0-r0/recipe-sysroot-native/usr/bin/dnf [...] ' 返回 1:

依赖关系已解决。

IMAGE_FEATURES_append = " dev-pkgs"

我还在我的local.conf 中设置了DISTRO_FEATURES_remove = "busybox x11 wayland" 和DISTRO_FEATURES_append = " systemd opengl aufs"。
如果我删除 inherit populate_sdk_qt5 行，构建运行良好，但在这种情况下，我当然不会为我的 SDK 获得 make。
我发现了什么
我发现不同的人有同样的问题（例如 here），但没有人得到答案。
我检查了 nativesdk-cmake 以及 nativesdk-qtbase_git 配方（两者都未更改标准）以查看文件是在哪里创建的，对我来说这两个都没有问题：
natives-qtbase_git.bb:
fakeroot do_generate_qt_environment_file() {
mkdir -p ${D}${SDKPATHNATIVE}/environment-setup.d/
script=${D}${SDKPATHNATIVE}/environment-setup.d/qt5.sh

echo 'export QMAKESPEC=`qmake -query QT_INSTALL_LIBS`${QT_DIR_NAME}/mkspecs/linux-oe-g++' >> $script
# Use relocable sysroot
sed -i -e 's:${SDKPATHNATIVE}:$OECORE_NATIVE_SYSROOT:g' $script
}
cmake-3.7.2.bb:
do_install_append_class-nativesdk() {
mkdir -p ${D}${datadir}/cmake
install -m 644 ${WORKDIR}/OEToolchainConfig.cmake ${D}${datadir}/cmake/
mkdir -p ${D}${SDKPATHNATIVE}/environment-setup.d
install -m 644 ${WORKDIR}/environment.d-cmake.sh ${D}${SDKPATHNATIVE}/environment-setup.d/cmake.sh
}
environment.d-cmake.sh:
alias cmake="cmake -DCMAKE_TOOLCHAIN_FILE=$OECORE_NATIVE_SYSROOT/usr/share/cmake/OEToolchainConfig.cmake"
为了尝试，我继续执行/home/ubuntu/workspace/bbb/build-toaster-2/tmp/work/my_machine-poky-linux-gnueabi/my-image-dev/1.0-r0/recipe-sysroot-native/usr/bin/dnf
脚本来自/home/ubuntu/workspace/bbb/build-toaster-2/tmp/work/my_machine-poky-linux-gnueabi/my-image-dev/1.0-r0/recipe-sysroot-native
这给了我以下错误消息：
Traceback (most recent call last): File "/home/ubuntu/workspace/bbb/build-toaster-2/tmp/work/my-machine-poky-linux-gnueabi/my-image-dev/1.0-r0/recipe-sysroot-native/usr/bin/dnf.real", line 57, in <module> from dnf.cli import main ImportError: No module named 'dnf'
dnf 模块似乎存在：
<path as above>/recipe-sysroot-native$ find -name dnf
./usr/lib/python3.5/site-packages/dnf
./usr/bin/dnf
./etc/dnf
./etc/bash_completion.d/dnf
./etc/logrotate.d/dnf
你能看出我做错了什么吗？我真是一头雾水……
