重新打开Python中的文件赋予权限错误

问题描述：

我已搜查，并试图实施解决方案，这里建议： Errno 13 Permission denied: 'file.mp3' Python Error while re-opening sound file in python 重新打开Python中的文件赋予权限错误

但似乎没有要这个有什么好的解决方案。这里是我的代码，任何人都可以告诉我我在做什么这里错了：

#!/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

你能让你的问题更具体吗？ Stackoverflow不是一个只是向人们抛出代码并期望他们能够看到错误的网站。代码中哪里会崩溃？ –

我怀疑的第一件事是，你只是没有正确地关闭文件，所以当你试图重新打开它时，它已经被使用。看起来你正在对一个字符串变量（'sound_file.close（）'）调用'.close（）'。你确定这就是你应该用Mutagen做的事情吗？我不会花时间为您阅读文档。 –

非常感谢，很抱歉，这是我第一次使用stackoverflow。下一次我会做得更好:) 实际上，你帮助指向了我，并在play_music函数中添加了mp3.save（）帮助我取得了进展。谢谢！ – BrotherHelmer

答

所以我找到了修复的原始线程之一，我已经去了。此修复程序是实现一个delete（）的函数，像这样：

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

和改变play_music（）函数，所以它包括最终删除（）函数（和我删除的sound_file.close（）语句课程）。
