debhelper指示使用python3，但使用python2运行setup.py

Question

我很难用dh为python 3(而不是python 2)创建包。我使用setup.py，当与python3一起调用时，它是为python3构建的，我为py3k有一个单独的debian目录，所以我只想为该版本构建。

debian/rules看起来是这样的：

export DH_VERBOSE=1
%:
    dh $@ --with python3

debian/control有所有常见的东西，包括X-Python3-Version

现在，当我运行fakeroot debian/rules binary时，setup.py是使用python而不是python3运行的，尽管有--with python3

$ fakeroot debian/rules binary
dh binary --with python3
   dh_auto_build
pyversions: missing X(S)-Python-Version in control file, fall back to debian/pyversions
pyversions: missing debian/pyversions file, fall back to supported versions
    python setup.py build --force
[...]

有什么问题吗？

解决方案是将--buildsystem=pybuild添加到debian/rules中，这样看起来如下所示：

%:
    dh $@ --with python3 --buildsystem=pybuild
