重新打開Python中的文件賦予權限錯誤

我已搜查，並試圖實施解決方案，這裏建議： Errno 13 Permission denied: 'file.mp3' Python Error while re-opening sound file in python 重新打開Python中的文件賦予權限錯誤

但似乎沒有要這個有什麼好的解決方案。這裏是我的代碼，任何人都可以告訴我我在做什麼這裏錯了：

#!/usr/bin/env python3 
# Requires PyAudio and PySpeech. 
import time, os 
import speech_recognition as sr 
from gtts import gTTS 
import pygame as pg 
import mutagen.mp3 

#Find out what input sound device is default (use if you have issues with microphone) 
#import pyaudio 
#sdev= pyaudio.pa.get_default_input_device() 

def play_music(sound_file, volume=0.8): 
    ''' 
    stream music with mixer.music module in a blocking manner 
    this will stream the sound from disk while playing 
    ''' 
    # set up the mixer, this will set it up according to your sound file 
    mp3 = mutagen.mp3.MP3(sound_file) 
    pg.mixer.init(frequency=mp3.info.sample_rate) 
    pg.mixer.music.set_volume(volume) 
    try: 
     pg.mixer.music.load(sound_file) 
     print("HoBo Sound file {} loaded!".format(sound_file)) 
    except pg.error: 
     print("HoBo Sound file {} not found! ({})".format(sound_file, pg.get_error())) 
     return 
    pg.mixer.music.play() 
    while pg.mixer.music.get_busy() == True: 
     continue 
    pg.mixer.quit() 
    sound_file.close() 

def speak(audioString): 
    print(audioString) 
    tts = gTTS(text=audioString, lang='en') 
    tts.save("audio.mp3") 
    # pick a mp3 file in folder or give full path 
    sound_file = "audio.mp3" 
    # optional volume 0 to 1.0 
    volume = 0.6 
    play_music(sound_file, volume) 

def audioIn(): 
    # Record Audio from Microphone 
    r = sr.Recognizer() 
    with sr.Microphone() as source: 
     print("Say something!") 
     audio = r.listen(source) 

    # Google Speech Recognition 
    try: 
     # for testing purposes, we're just using the default API key 
     # to use another API key, use `r.recognize_google(audio, key="GOOGLE_SPEECH_RECOGNITION_API_KEY")` 
     # instead of `r.recognize_google(audio)` 
     data = r.recognize_google(audio) 
     print("You said: ", data) 

    except sr.UnknownValueError: 
     print("Google Speech Recognition could not understand audio") 
    except sr.RequestError as e: 
     print("Could not request results from Google Speech Recognition service; {0}".format(e)) 

    return data 


def hobo(data): 
    if "how are you" in data: 
     speak("I am fine") 

    if "what time is it" in data: 
     speak(time.ctime()) 

    if "where is" in data: 
     data = data.split(" ") 
     location = data[2] 
     speak("Hold on Sir, I will show you where " + location + " is.") 
     os.system("chromium-browser https://www.google.nl/maps/place/" + location + "/&amp;") 

# Starts the program 
#time.sleep(2) 
speak("Testing") 

while(data != "stop"): 
    data = audioIn() 
    hobo(data) 
else: 
    quit

你能讓你的問題更具體嗎？ Stackoverflow不是一個只是向人們拋出代碼並期望他們能夠看到錯誤的網站。代碼中哪裏會崩潰？ –

我懷疑的第一件事是，你只是沒有正確地關閉文件，所以當你試圖重新打開它時，它已經被使用。看起來你正在對一個字符串變量（'sound_file.close（）'）調用'.close（）'。你確定這就是你應該用Mutagen做的事情嗎？我不會花時間爲您閱讀文檔。 –

非常感謝，很抱歉，這是我第一次使用stackoverflow。下一次我會做得更好:) 實際上，你幫助指向了我，並在play_music函數中添加了mp3.save（）幫助我取得了進展。謝謝！ – BrotherHelmer

所以我找到了修復的原始線程之一，我已經去了。此修復程序是實現一個delete（）的函數，像這樣：

def delete(): 
    time.sleep(2) 
    pg.mixer.init() 
    pg.mixer.music.load("somefilehere.mp3") 
    os.remove("audio.mp3")

和改變play_music（）函數，所以它包括最終刪除（）函數（和我刪除的sound_file.close（）語句課程）。
