详细

我问，因为我想安装Aggdraw（包装的C++反谷物几何绘图库），这在Python 2.6-7的作品，但在关于Python 3.4（Windows 7的32位错误结果在命令行中通过“PATH = C：/ Python27 [或Python34]”和“python setup.py install”）。我的希望是为Python 3重振这个惊人的包装模块，并希望这里的其他人在帮忙时会很有趣。

我可以在没有任何问题的情况下在Python 2.6和2.7上编译它，并且我有Visual C++ 2008和2010，所以它不是编译器问题。问题似乎在实际的.cxx包装代码中。

是不是因为Aggdraw包装器只是用Python 2x编写的（大约10年前），所以它没有考虑到Python 3x中可能出现的问题？我最好的猜测是，由于3.4版本中的弃用和更改功能，wrapper未能将某些C++对象/类型转换为Python。

如果有人可以帮助我确定故障部件是什么（请参阅下面的命令行错误代码），我可能愿意通过.cxx包装代码更改必要的部件。如果我们修复了这个问题，那么我会通过链接到“复活”的封装代码来更新这篇文章。

如果Python 2和3包装之间应该没有区别，那么为什么我会在Py3中获取错误代码而不是Py2？

谢谢！
