, there is an error indicating missing quantlib_wrap.cpp

推荐答案
quantlib_wrap.cpp
由SWIG使用存储库中的源生成.如果安装了SWIG,则可以生成它(请参见 https://www.quantlib. org/install/windows-python.shtml );但是如果您没有修改源的计划,建议您:
quantlib_wrap.cpp
is generated by SWIG using the sources in the repository. If you have SWIG installed, you can generate it (see https://www.quantlib.org/install/windows-python.shtml); but if you don't have plans to modify the sources, I suggest that you either:
-
而不是从GitHub克隆存储库,而是下载正式版本(请参见 https://www.quantlib.org/download.shtml );已发布的资源包括
quantlib_wrap.cpp
;
instead of cloning the repo from GitHub, download an official release (see https://www.quantlib.org/download.shtml); released sources include
quantlib_wrap.cpp
;
或更好的方法,如上面链接的安装页面中所述,请尝试运行
or better yet, as suggested in the install page linked above, try running
pip install QuantLib-Python
查看PyPI是否提供了预编译的Python模块.如果成功的话,您将无需自己编译即可进行设置.
to see if a precompiled Python module is available from PyPI. If that succeeds, you'll be set without having to compile the thing yourself.
