Python3.6:在安装了_QuantLib和QuantLib之后，没有名为QuantLib的模块

Question

我正试图在MacOSX10.12.5塞拉利昂和Python3.6.1上安装QuantLib和SWIG。但是收到错误消息：

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在这个关于QuantLib用户邮寄名单的线程中给出了一个非常有用的建议，我实现了这个线程并取得了一些进展，但是我仍然无法完成Python3.6的安装。

我已经成功地为Python2构建了QuantLib。

我还尝试在下面构建带有动态加载的QuantLib (例如，在下面的步骤#5中，我使用rm‘’ed /usr/local/lib/libQuantLib*，然后在没有‘-禁用-共享-启用-静态’的情况下重新运行进程，但是也失败了.*(.)

有人有什么建议吗？提前谢谢你。

如何安装QuantLib

1. 安装：

- Xcode 8.3.3
- Apple’s Command Line Developer Tools, by running on terminal: xcode-select --install
- brew
- boost, by running on terminal: brew install boost

​

1. 从sourceforge下载tars：

- QuantLib 1.10
- QuantLib-SWIG 1.10

​

1. 将上面的内容解压缩到主目录: /Users/tf/
2. 在终端上运行: cd ~/QuantLib-1.10切换到QuantLib-1.10
3. 在终端上运行：#./配置-具有-增强-包括=//usr/local/包括/-与-boost-lib=/usr/local/-前缀=/usr/local/ CXXFLAGS='-O2 -stdlib=libc++ -mmacosx-version-min=‘-stdlib=libc++-mmacosx-版本-min=10.9’-禁用-共享-启用-静态
4. 在终端上运行: make && sudo make install
5. 通过在终端上运行来测试C++安装: cd示例/百慕大installation && g++ -i/usr/g++/include/i/usr/local/include/ BermudanSwaption.cpp -o include应答-L/usr/local/lib/ -lQuantLib
6. 在终端上运行: cd ~/QuantLib-swg-1.10在终端上运行:/配置CXXFLAGS='-O2 -stdlib=libc++ -mmacosx-version-min=10.9‘LDFLAGS='-stdlib=libc++ -mmacosx-版本-min=10.9’
7. 在终端上运行C++ Python版本:CDPython&&/ setup.py /tf/anaconda/bin/python3.6 setup.py构建
8. 通过在终端上运行: /Users/tf/ anaconda /bin/python3.6 setup.py安装到anaconda
9. 在终端上运行检查: /Users/tf/anaconda/bin/python3.6 setup.py测试
