构建导入库libpython27.a时出现f2py错误：找不到指定的文件 [英] f2py error while building import library libpython27.a: cannot find the file specified

问题描述

我试图用f2py编译Fortran代码到共享库中，导入并在Windows 10中使用python。（它在我的Linux分区上工作正常）。我安装了anaconda，并使用 conda安装我安装了numpy，scipy，jupyter和matplotlib，都没有错误。我再次使用anaconda安装Fortran编译器，使用 conda install mingw ，没有任何问题。当我运行

I am trying to compile a fortran code using f2py into a shared library to import and use in python on windows 10. (It works fine on my Linux partition.) I installed anaconda, and using conda install I installed numpy, scipy, jupyter, and matplotlib, all without errors. I again used anaconda to install fortran compilers using conda install mingw without any problems. When I run

python C:\Users\user_name\Anaconda2\Scripts\f2py.py -c --fcompiler=gnu95 --compiler=mingw32 -m foo foo.f

我得到以下输出底部的错误信息）：

I get the following output (error message at the bottom):

Looking for python27.dll
Building import library (arch=AMD64): "C:\Users\user_name\Anaconda2\libs\libpython27.a" (from C:\Users\user_name\Anaconda2\python27.dll)
error: [Error 2] The system cannot find the file specified

我可能会离开基地，但在我看来，编译进行得很顺利，试图组装一个python模块。存在 C：\ Users \ user_name\Anaconda2\python27.dll 文件。文件 C：\ Users \ user_name\Anaconda2\libs\libpython27.a 不存在。我检查了我能够在文件夹中创建文件（ C：\ Users \ user_name\Anconda2\libs\ ）。

I could be way off-base, but it looks to me like the compilation goes well, and the error occurs when trying to put together a python module. The file C:\Users\user_name\Anaconda2\python27.dll exists. The file C:\Users\user_name\Anaconda2\libs\libpython27.a does not exist. I checked that I was able to create files in the folder (C:\Users\user_name\Anaconda2\libs\).

推荐答案

刚才我有类似的设置（虽然使用Windows 7）也有同样的问题。一段时间后，我发现安装libpython包（ conda install libpython ）似乎解决了这个问题。

I had this same problem just now with a similar setup (though using Windows 7). After awhile, I found that installing the libpython package (conda install libpython) seemed to fix it.

我想使用描述 gendef / dlltool 6950787> 在这里也可以做到这一点。

I think using the gendef / dlltool approach described here would also do the trick.
