为 Yocto 添加 PyPi 包，无需 setup.py

Question

我正在使用 Yocto Kirkstone 为我的 Linux 设备创建映像。我想添加尚未作为 bitbake 配方存在的 PyPi 包“tinydb”。我使用了一个工具来创建一个可以进行 Bitbake 的工作配方。然而，当我尝试将这个食谱包含到我的图像中时，我遇到了以下失败。所以我可以构建包但不能安装它。我怎样才能解决这个问题？谢谢。

Reading package lists...
Building dependency tree...
Reading state information...
Package python3-tinydb is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'python3-tinydb' has no installation candidate

但是我可以成功地做到这一点：

bitbake -c cleansstate python3-tinydb && bitbake python3-tinydb

Bitbake 食谱：

图像中的图像安装线：

# Add python packages
IMAGE_INSTALL += "python3-tinydb"

编辑：我相信问题可能是 Yocto 的工作目录中没有“包”。这可能是因为没有setup.py来安装tinydb包：

您可以获取whl，然后手动提取它。像这样的东西：

inherit python3-dir

SRC_URI = "https://files.pythonhosted.org/packages/1c/c4/9a1721139a6087ab3df4ba99ac82da5d88f92b1ea5027b0c411ce09b1d70/tinydb-4.8.0-py3-none-any.whl;downloadfilename=tinydb-4.8.0-py3-none-any.zip"
SRC_URI[md5sum] = "46ae8775b63486a4248d9607fa7af1ce"

do_unpack[depends] += "unzip-native:do_populate_sysroot"

DEPENDS = "python3"

do_install() {
    install -d ${D}${libdir}/${PYTHON_DIR}/site-packages/tinydb
    install -d ${D}${libdir}/${PYTHON_DIR}/site-packages/tinydb-${PV}.dist-info

    install -m 644 ${WORKDIR}/tinydb/* ${D}${libdir}/${PYTHON_DIR}/site-packages/tinydb/
    install -m 644 ${WORKDIR}/tinydb-${PV}.dist-info/* ${D}${libdir}/${PYTHON_DIR}/site-packages/tinydb-${PV}.dist-info/
}

FILES:${PN} += "\
    ${libdir}/${PYTHON_DIR}/site-packages/tinydb \
    ${libdir}/${PYTHON_DIR}/site-packages/tinydb-${PV}.dist-info \
"

称其为

python3-tinydb_4.8.bb

或类似的名称。

注意：还没有尝试实际的配方（例如，您需要添加许可证信息），可能会有一些拼写错误，但这是以相对轻松的方式安装此类软件包的主要思想。
