Include python-dropbox in Yocto

My Python application uses Dropbox and I need to include this library in my Yocto image. I managed to generate a recipe for it with pipoe (pipoe -p dropbox). Here it is:

SUMMARY = "Official Dropbox API Client"
HOMEPAGE = "http://www.dropbox.com/developers"
AUTHOR = "Dropbox <dev-platform@dropbox.com>"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://LICENSE;md5=ef3219362ea5e452a18031af12f35eb6"

SRC_URI = "https://files.pythonhosted.org/packages/85/33/bffd4a7596f3280f8bd2796b4f09c5c701b99d5c8e68715351cc2b3eeca8/dropbox-10.3.0.tar.gz"
SRC_URI[md5sum] = "f6d1a30af7e202237d660213d22e48a7"
SRC_URI[sha256sum] = "5f296f13ee7c358ab41779a73c4922ed81199447566c1a4c8fbf23dbcda25e20"

S = "${WORKDIR}/dropbox-10.3.0"

RDEPENDS_${PN} = "python-requests python-six "

inherit setuptools

When I run it, it says:

| ERROR: Do not try to fetch `pytest-runner' for building. Please add its native recipe to DEPENDS.

and then

| raise DistributionNotFound(req, requirers)
| pkg_resources.DistributionNotFound: The 'pytest-runner' distribution was not found and is required by the application

so I added the following line to the generated recipe:

DEPENDS = "python3-pytest-runner-native "

But I still get the same error. Any idea?

Solution

Probably an issue with inconsistent Python version.

You inherit setuptools which is for python2. The RDEPENDS are for python2 dependencies. But you add python3-pytest-runner-native in DEPENDS.

I'd suggest finding out which python version to use for this software and use the same for all RDEPENDS, inherited classes (setuptools3 for python3), and DEPENDS.
