python 3.6：安装QuantLib和QuantLib-SWIG后没有名为_QuantLib的模块

标签： python-3.6 failed-installation quantlib quantlib-swig

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-

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QuantLib用户的这个主题中提出了一个非常有用的建议。 mailing list，我实现并取得了一些进展，但我仍然无法完成Python 3.6的安装。

我已经能够成功构建用于Python 2的QuantLib。

我还尝试使用下面的动态加载来构建QuantLib（即我使用/ usr / local / lib / libQuantLib *然后在没有＆＃39; - disable-shared --enable-static＆的情况下重新启动该过程＃39;在下面的步骤＃5中，但也失败了.... :(。）

有人有什么建议吗？提前谢谢。

我如何安装QuantLib

  1. 安装：

    • Xcode 8.3.3
    • Apple的命令行开发人员工具，通过在终端上运行：xcode-select --install
    • 冲泡
    • 通过在终端上运行来提升：brew install boost

  2. 从sourceforge下载tars：

    • QuantLib 1.10
    • QuantLib-SWIG 1.10

  3. 将以上内容解压缩到主目录：        /用户/ TF /

  4. 通过在终端上运行切换到QuantLib-1.10：        cd~ / QuantLib-1.10

  5. 在终端上运行：        ＃。/ configure --with-boost-include = / usr / local / include / --with-boost-lib = / usr / local / lib / --prefix = / usr / local / CXXFLAGS =＆＃39; - O2 -stdlib = libc ++ -mmacosx-version-min = 10.9＆＃39; LDFLAGS =＆＃39; -stdlib = libc ++ -mmacosx-version-min = 10.9＆＃39; --disable-shared --enable-static

  6. 在终端上运行：        制造＆amp;＆amp; sudo make install

  7. 通过在终端上运行来测试C ++安装：        cd Examples / BermudanSwaption＆amp;＆amp; g ++ -I / usr / local / include / -I / usr / local / include / boost BermudanSwaption.cpp -o bermudanswaption -L / usr / local / lib / -lQuantLib

  8. 通过在终端上运行切换到QuantLib-SWIG-1.10：        cd~ / QuantLib-SWIG-1.10 在终端上运行：        ./configure CXXFLAGS =＆＃39; -O2 -stdlib = libc ++ -mmacosx-version-min = 10.9＆＃39; LDFLAGS =＆＃39; -stdlib = libc ++ -mmacosx-version-min = 10.9＆＃39;

  9. 通过在终端上运行来制作C ++ Python版本：        cd Python＆amp;＆amp; /Users/tf/anaconda/bin/python3.6 setup.py build

  10. 通过在终端上运行安装到anaconda：        /Users/tf/anaconda/bin/python3.6 setup.py install

  11. 在终端上运行检查：        /Users/tf/anaconda/bin/python3.6 setup.py test
