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

本文介绍了python 3.6:安装QuantLib和QuantLib-SWIG后，没有名为_QuantLib的模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试图在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:

I am trying to install QuantLib and Python QuantLib-SWIG on Mac OSX 10.12.5 Sierra and Python 3.6.1., but get error messages:

ImportError: dlopen(build/lib.macosx-10.7-x86_64-
3.6/QuantLib/_QuantLib.cpython-36m-darwin.so, 2): Symbol not found: __

Expected in: flat namespace

以及:

ModuleNotFoundError: No module named '_QuantLib'

Luigi在QuantLib用户的邮件列表中对此线程给出了非常有用的建议，我实现并取得了一些进展，但仍然无法完成Python 3.6的安装.

Luigi gave a very useful suggestion in this thread on the QuantLib users' mailing list, which I implemented and made some progress, but I still cannot finish installation for Python 3.6.

我已经能够成功构建适用于Python 2的QuantLib.

I have been able to successfully build QuantLib for Python 2.

我还尝试使用下面的动态加载来构建QuantLib(即我rm/usr/local/lib/libQuantLib *，然后在步骤#5中重新运行过程，而没有使用"--disable-shared --enable-static"下面，但是也失败了....:(.)

I also tried to build QuantLib with dynamic loading below (i.e. I rm'ed /usr/local/lib/libQuantLib* and then reran the process without '--disable-shared --enable-static' in step #5 below, but that also failed.... :(.)

有人有什么建议吗?预先谢谢你.

Anyone have any advice? Thank you in advance.

  • 酿造
  • 增强功能，通过在终端上运行:brew install boost

从sourceforge下载tar:

Download the tars from sourceforge:

  • QuantLib 1.10
  • QuantLib-SWIG 1.10

将以上内容提取到主目录: /Users/tf/

Extract the above to home directory: /Users/tf/

通过在终端上运行，切换到QuantLib-1.10: cd〜/QuantLib-1.10

Switch to QuantLib-1.10 by running on terminal: cd ~/QuantLib-1.10

在终端上运行: #./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

Run on terminal: #./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
