Yocto setup.py 需要 pyserial

Question

我正在尝试将 https://github.com/kliment/Printrun 打包到 Yocto 食谱中，但无法正常工作。我的食谱目前看起来如下：

LICENSE = "AGPLv3"
LIC_FILES_CHKSUM = "file://COPYING;md5=d32239bcb673463ab874e80d47fae504"

PV = "2.7"
SRCREV = "0193a9dbe31458c45059bf2dcb0a9905b7bb06fc"
SRC_URI = "git://github.com/kliment/Printrun.git;protocol=git;branch=master"

RDEPENDS_${PN} = "python-cython \
                  python-pyserial \
"

S = "${WORKDIR}/git"

inherit distutils

我假设这是我需要做的，因为它有一个继承自 distutils 的 setup.py？如果是这样，这不起作用，我收到一个错误，抱怨缺少串行模块：

DEBUG: Executing shell function do_compile
WARNING: Failed to cythonize: No module named Cython.Build
Traceback (most recent call last):
  File "setup.py", line 36, in <module>

    from serial import Serial, SerialException, PARITY_ODD, PARITY_NONE

我也希望能够用cython编译小型cythonable模块。由于某种原因，cython 和 psyerial 都不可用，即使我将它们添加为 rdepends，我做错了什么？

您仅在运行时添加了对 python cython 的依赖。我猜你还需要添加编译。

DEPENDS_${PN} = "python-cython \
                  python-pyserial"
