WinError 2 系统找不到指定的文件（Python）

Question

我有一个 Fortran 程序，想在 python 中为多个文件执行它。我有 2000 个输入文件，但在我的 Fortran 代码中，我一次只能运行一个文件。我应该如何在python中调用Fortran程序？

我的脚本：

 import subprocess
import glob
input = glob.glob('C:/Users/Vishnu/Desktop/Fortran_Program_Rum/*.txt')
output = glob.glob('C:/Users/Vishnu/Desktop/Fortran_Program_Rum/Output/')
f = open("output", "w")
for i in input:
    subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])
f.write(i)

错误：

 runfile('C:/Users/Vishnu/Desktop/test_fn/test.py', wdir='C:/Users/Vishnu/Desktop/test_fn')
Traceback (most recent call last):

   File "<ipython-input-3-f8f378816004>", line 1, in <module>
runfile('C:/Users/Vishnu/Desktop/test_fn/test.py', wdir='C:/Users/Vishnu/Desktop/test_fn')

  File "C:\Users\Vishnu\Anaconda3\lib\site-packages\spyder\utils\site\sitecustomize.py", line 866, in runfile
execfile(filename, namespace)

  File "C:\Users\Vishnu\Anaconda3\lib\site-packages\spyder\utils\site\sitecustomize.py", line 102, in execfile
exec(compile(f.read(), filename, 'exec'), namespace)

  File "C:/Users/Vishnu/Desktop/test_fn/test.py", line 30, in <module>
subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])

  File "C:\Users\Vishnu\Anaconda3\lib\subprocess.py", line 707, in __init__
restore_signals, start_new_session)

  File "C:\Users\Vishnu\Anaconda3\lib\subprocess.py", line 990, in _execute_child
startupinfo)

FileNotFoundError: [WinError 2] The system cannot find the file specified

编辑：

 import subprocess
import os
input = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/*.txt')
output = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/Output/')
f = open("output", "w")
for i in input:
    exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe')
    fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/test_fn/test_f2py.f95')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])
    f.write(i)

错误：

 FileNotFoundError: [WinError 2] The system cannot find the file specified

我改变了我的脚本如下：但错误是一样的

input = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/*.txt')
output = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/Output/')
f = open("output", "w")
for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe')
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/test_fn/test_f2py.f95')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])
    f.write(i)

错误：2

 FileNotFoundError: [WinError 2] The system cannot find the file specified

错误：3 - 15-03-2017

 import subprocess

f = open('output', 'w+')
for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe')
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)
    f.write(i)

\*\* 错误 **

Popen 需要一个用于非 shell 调用的字符串列表和一个用于 shell 调用的字符串。

使用 shell=True 调用 subprocess.Popen：

 process = subprocess.Popen(command, stdout=tempFile, shell=True)

希望这可以解决您的问题。
