我已经安装了QuantLib和boost(我猜对了(。所有示例在 C/C++ 到 Visual Studio 2017 中运行良好。
现在我想安装QuantLib-Python版本。我有一个类似于
通过 QuantLib-SWIG 绑定
但是，我在设置环境变量时删除了=符号周围的空格。(我还通过我的电脑->属性->高级系统设置->环境变量添加了环境变量的路径(，但是QuantLib python的构建一直不起作用。我得到了以下输出

编辑更新
感谢路易吉·巴拉比奥的善意回答，我正确地设置了QL_DIR。现在我收到的错误消息如下

警告"无法检测到 QuantLib 安装"意味着安装脚本无法读取QL_DIR环境变量。 与您链接的问题一样，您应该将其设置为 QuantLib 文件夹的路径。 设置后，可能需要重新启动要从中生成包装器的命令提示符。
(也就是说，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，我看到您仍然收到错误"无法打开包含文件：'ql/version.hpp'"。 这表明包含目录设置不正确，实际上您的命令行包含一个无法工作的开关-IC:opt-libsQuantLib-1.13;C:opt-libsQuantLib-1.13lib;C:opt-libsQuantLib-1.13ql，因为-I不采用路径列表;它应该根据您的QL_DIR-IC:opt-libsQuantLib-1.13，我想这是C:opt-libsQuantLib-1.13- 我说得对吗？
简而言之，我会检查从命令提示符下看到的QL_DIR值;您可以使用
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。
