我已经安装了QuantLib和boost(我猜对了)。所有这些例子都可以通过Visual Studio 2017在C / C ++中正常运行。
现在我想安装QuantLib-Python版本。我有类似
的问题Python binding through QuantLib-SWIG
但是,当我设置环境变量时,我删除了=
符号周围的空格。 (我还通过“我的电脑” - >“属性 - >高级系统设置 - >环境变量”添加了environemnt变量的路径,但是QuantLib python的构建仍然无法正常工作。我得到了以下输出
(base) C:\opt-libs\QuantLib-SWIG-1.13\Python>python setup.py build

running build_py
running build_ext
warning: unable to detect QuantLib installation

编辑更新
感谢Luigi Ballabio的回答,我正确地设置了QL_DIR
。现在我得到的错误消息是以下

答案 0 :(得分:1)
警告"无法检测QuantLib安装"表示安装脚本无法读取QL_DIR
环境变量。与您链接的问题一样,您应将其设置为QuantLib文件夹的路径。设置之后,可能必须重新启动从中构建包装器的命令提示符。
(这就是说,在构建包装器之前,请尝试运行
pip install QuantLib-Python
根据您的Python版本,您可能会获得预编译的二进制文件。)
更新:设置QL_DIR
后,我发现您仍然收到错误"无法打开包含文件:' ql / version.hpp&# 39;&#34 ;.这指向包含目录未正确设置,实际上您的命令行包含一个无法正常工作的开关-IC:\opt-libs\QuantLib-1.13;C:\opt-libs\QuantLib-1.13\lib;C:\opt-libs\QuantLib-1.13\ql
,因为-I
不会记录路径列表;它应该是-IC:\opt-libs\QuantLib-1.13
基于您的QL_DIR
,我认为C:\opt-libs\QuantLib-1.13
- 我是否正确?
简而言之,我从命令提示符处查看QL_DIR
的值;你可以用
echo %QL_DIR%
如果是路径列表,请将其重置为指向QuantLib目录的单个路径。
