我正在努力使用dh为python 3创建包（而不是为python 2创建包）。我使用setup.py，当与python3一起调用时，它为python 3构建。对于py3k，我有一个单独的debian目录，所以我只想为那个版本构建。
debian/rules看起来像这样：
export DH_VERBOSE=1
%:
dh $@ --with python3
debian/control具有所有常见的东西，包括X-Python3-Version:

现在，当我运行fakeroot debian/rules binary时，setup.py使用python而不是python3运行，尽管--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
[...]
怎么了？
解决方案是将--buildsystem=pybuild添加到debian/rules中，使其看起来像这样：
%:
dh $@ --with python3 --buildsystem=pybuild
