f2py - 无法打开模块文件：没有这样的文件或目录

问题描述 投票：0回答：1

我正在尝试创建一个在 Python 中使用的 Fortran 模块，但它无法在 Windows 上运行，因为 

Cannot open module file 'fmodule.mod' for reading at (1): No such file or directory
。

我有这个脚本

module.f90
：

module fmodule
contains
   subroutine sub(a)
      real a(3)
      a(1) = 1.0
   end subroutine sub
end module fmodule

并尝试直接运行f2py

python -m numpy.f2py -c -m module module.f90

或带有签名文件

python -m numpy.f2py module.f90 -m module -h module.pyf
python -m numpy.f2py -c module.pyf module.f90

它返回：

那么，为什么我会遇到这个问题？我需要重新安装一些东西吗？还是我做错了什么？

如果需要的话，我对重要事情的看法：

Python 3.11.7
Numpy: 1.26.2
f2py: 1.26.2
GNU Fortran (GCC): 13.2.0
Microsoft Windows: 10.0.19045.3693

@VladimirFГероямслава 注意到，f2py 正在更改我的用户名，所以我强制文件夹创建文件：

python -m numpy.f2py -c -m fmodule module.f90 --build-dir C:\Users\tanus.szabo\CODE\PySolidGUI\teste\temp

它创建了具有以下结构的文件夹：

C:\Users\tanus.szabo\CODE\PySolidGUI\teste\temp\
┣ Release\
┃ ┣ .libs\
┃ ┣ Users\
┃ ┃ ┗ tanus.szabo\
┃ ┃   ┗ CODE\
┃ ┃ ┃   ┗ PySolidGUI\
┃ ┣ fmodule.mod
┃ ┗ module.o
┗ src.win-amd64-3.11\
  ┣ fmodule-f2pywrappers2.f90
  ┣ fmodulemodule.c
  ┣ fortranobject.c
  ┗ fortranobject.h

但它仍然返回相同的错误：

我明白了！

在问题“BUG：f2py没有正确包装函数”的这个答案之后，我添加了第三步来编译模块：

:: Create function signatures
f2py module.f90 -m fortranmodule -h module.pyf
:: Generate module 
gfortran -c -O3 module.f90
:: Build extension module
f2py -c module.pyf module.f90 --fcompiler=gnu95

它不仅适用于我的帖子示例，而且适用于我的实际模块！
