Python 2:系统找不到在WinError中使用FluidSynth指定的文件？

Question

尝试制作程序的一部分，其中MIDI文件被转换为不同的文件类型。下面是一个无法工作的代码示例：

from midi2audio import FluidSynth
midfile = "F:\\ai nea\\Actual Project\\"+input()
output = "F:\\ai nea\\Actual Project\\output.mp3"
soundfont= "F:\\ai nea\\Actual Project\\FluidR3 GM.sf2"
fs = FluidSynth(sound_font=soundfont)
fs.midi_to_audio(midfile,output)

这是一个例外：

Traceback (most recent call last):
  File "F:/ai nea/Actual Project/contest.py", line 6, in <module>
    fs.midi_to_audio(midfile,output)
  File "C:\Users\Will\AppData\Local\Programs\Python\Python37\lib\site-packages\midi2audio.py", line 46, in midi_to_audio
    subprocess.call(['fluidsynth', '-ni', self.sound_font, midi_file, '-F', audio_file, '-r', str(self.sample_rate)])
  File "C:\Users\Will\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 339, in call
    with Popen(*popenargs, **kwargs) as p:
  File "C:\Users\Will\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 800, in __init__
    restore_signals, start_new_session)
  File "C:\Users\Will\AppData\Local\Programs\Python\Python37\lib\subprocess.py", line 1207, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

有什么想法吗？

找不到您的程序"fluidsynth.exe“。您可以将程序的位置放在PATH环境变量中来修复此问题。
