运行Python Swig时出现问题

我正在尝试运行Python中的Quantlib。我有它运行，但必须作出新的清洁安装，现在我挣扎着让它再次运行。我认为主要的问题似乎在包装上

我的操作系统是Windows 10，我使用的是python 3.6.3 | Anaconda custom（64位）和Visual Studio Community 2015。Quantlib通常在VS15中编译（64位），并且也在运行。我只编译Quantlib解决方案，而不是完整的包

我的QL输出是：

QuantLib-vc140-x64-mt

然后，我按照以下定义设置所有环境变量：

INCLUDE=C:\QuantAna\boost_1_65_0
LIB=C:\QuantAna\boost_1_65_0\lib64-msvc-14.0
Path=C:\Users\mcm\Anaconda3;C:\Users\mcm\Anaconda3\Library\mingw-w64\bin;C:\Users\mcm\Anaconda3\Library\usr\bin;C:\Users\mcm\Anaconda3\Library\bin;C:\Users\mcm\Anaconda3\Scripts;C:\Users\mcm\Anaconda3\bin;C:\ProgramData\Oracle\Java\javapath;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\MySQL\MySQL Utilities 1.6\;C:\WINDOWS\system32\config\systemprofile\.dnx\bin;C:\Program Files\Microsoft DNX\Dnvm\;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft Emulator Manager\1.0\;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\Users\mcm\Anaconda3;C:\Users\mcm\Anaconda3\Library\mingw-w64\bin;C:\Users\mcm\Anaconda3\Library\usr\bin;C:\Users\mcm\Anaconda3\Library\bin;C:\Users\mcm\Anaconda3\Scripts;C:\Users\mcm\AppData\Local\Microsoft\WindowsApps;C:\QuantAna\swigwin-3.0.12;
QL_DIR=C:\QuantAna\QuantLib-1.11

然后，我使用Anaconda提示符在python中运行QL，如下所示：

我不确定问题出在哪里。我尝试了很多东西，比如32位othe VS版本等，结果都是一样的。此外，当更改swig文件中的某些内容（以前工作的内容）时，构建也会失败。所以我想一定是包装里的东西

您的安装没有问题。测试中出现了一个问题，最近出现了这个问题（请参阅）。该问题已修复（），但该修复尚未发布，因此出现了您看到的错误

---

您可以继续安装您构建的模块。

非常感谢。我真的疯了：）。祝你星期天愉快。
