嗨，我正在尝试使用 SWIG 绑定为 python 安装 quantlib，但出现以下错误。我在 Windows 7 上，有 Python 2.7 64 位，并使用 MS Visual Studio Express 2008 构建了 quantlib 1.5，我已经执行了https://jenshuebel.wordpress.com/2009/02/12/visual-c-中列出的所有步骤2008-express-edition-and-64-bit-targets/编译 64 位代码：

running build_py
copying QuantLib\QuantLib.py -> build\lib.win-amd64-2.7\QuantLib
