python3.6：安装 QuantLib 和 QuantLib-SWIG 后没有名为 _QuantLib 的模块

Question

我正在尝试在 Mac OSX 10.12.5 Sierra 和 Python 3.6.1. 上安装 QuantLib 和 Python QuantLib-SWIG，但收到错误消息:

ImportError: dlopen(build/lib.macosx-10.7-x86_64-
3.6/QuantLib/_QuantLib.cpython-36m-darwin.so, 2): Symbol not found: __ 
ZN8QuantLib10DateParser14parseFormattedERKSsS2_
Referenced from: build/lib.macosx-10.7-x86_64-
3.6/QuantLib/_QuantLib.cpython-36m-darwin.so
Expected in: flat namespace
in build/lib.macosx-10.7-x86_64-3.6/QuantLib/_QuantLib.cpython-36m-darwin.so

以及：

ModuleNotFoundError: No module named '_QuantLib'

Luigi 在这个线程中对 QuantLib 用户的 mailing list 提出了一个非常有用的建议，我实施并取得了一些进展，但我仍然无法完成 Python 3.6 的安装。

我已经能够为 Python 2.

成功构建 QuantLib

我还尝试使用下面的动态加载构建 QuantLib（即我 rm'ed /usr/local/lib/libQuantLib* 然后在下面的第 5 步中不使用 '--disable-shared --enable-static' 重新运行该过程，但这也失败了.... :(.)

有人有什么建议吗？提前谢谢你。

我是如何尝试安装 QuantLib

安装：
- Xcode 8.3.3
- Apple 的命令行开发人员工具，通过运行在终端上：xcode-select --install
- 酿造
- boost，通过运行在终端上：brew install boost
从 sourceforge 下载 tars：
- 量化库 1.10
- QuantLib-SWIG 1.10
将以上内容解压到主目录： /Users/tf/
在终端上通过运行切换到 QuantLib-1.10： cd ~/QuantLib-1.10
运行在终端上： #./configure --with-boost-include=/usr/local/include/ --with-boost-lib=/usr/local/lib/ --prefix=/usr/local/ CXXFLAGS='-O2 -stdlib= libc++ -mmacosx-version-min=10.9' LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9' --disable-shared --enable-static
运行在终端上： make && sudo make install
通过运行在终端上测试 C++ 安装： cd Examples/BermudanSwaption && g++ -I/usr/local/include/ -I/usr/local/include/boost BermudanSwaption.cpp -o bermudanswaption -L/usr/local/lib/ -lQuantLib
在终端上通过运行切换到 QuantLib-SWIG-1.10： cd ~/QuantLib-SWIG-1.10 运行在终端上： ./configure CXXFLAGS='-O2 -stdlib=libc++ -mmacosx-version-min=10.9' LDFLAGS='-stdlib=libc++ -mmacosx-version-min=10.9'
通过运行在终端上制作 C++ Python 版本： cd Python && /Users/tf/anaconda/bin/python3.6 setup.py build
在终端上通过运行安装到 anaconda： /Users/tf/anaconda/bin/python3.6 setup.py 安装
在终端上通过运行检查： /Users/tf/anaconda/bin/python3.6 setup.py 测试
