Python 3.x 在python中从zip加载音频文件时出错

我正在制作一个游戏，需要从.zip文件加载一些受密码保护的音频文件，但我遇到以下错误：

io.UnsupportedOperation: seek
io.UnsupportedOperation: seek
io.UnsupportedOperation: seek
b'hey you did it!' #THIS IS FROM THE PROGRAM
Traceback (most recent call last):
  File "C:\Python36\lib\zipfile.py", line 849, in read
    data = self._read1(n)
  File "C:\Python36\lib\zipfile.py", line 917, in _read1
    data += self._read2(n - len(data))
  File "C:\Python36\lib\zipfile.py", line 949, in _read2
    data = self._fileobj.read(n)
  File "C:\Python36\lib\zipfile.py", line 705, in read
    self._file.seek(self._pos)
AttributeError: 'NoneType' object has no attribute 'seek'

下面是我的代码：

from zipfile import ZipFile
from PIL import Image
from io import BytesIO
import pygame
from pygame.locals import *
import pyganim
import sys

pygame.init()
root = pygame.display.set_mode((320, 240), 0, 32)
pygame.display.set_caption('image load test')


#THIS IS HOW TO LOAD IMAGES (WORKS)
with ZipFile("spam.zip", 'r') as archive:
    mcimg = archive.read('a.png', pwd=b'onlyforthedev')
    mc = pygame.image.load(BytesIO(mcimg))
    anime = pyganim.PygAnimation([(mc, 100),
                                  (mc, 100)])
    anime.play()

#THIS IS HOW TO LOAD MUSIC (DOES NOT WORK)
with ZipFile('spam.zip') as zippie:
    with zippie.open('zora.mp3', pwd=b'onlyforthedev') as zora:
        pygame.mixer.music.load(zora)
        pygame.mixer.music.play(-1)

#THIS IS HOW TO LOAD TEXT (WORKS)
with ZipFile('spam.zip') as myzip:
    with myzip.open('eggs.txt', pwd=b'onlyforthedev') as myfile:
        print(myfile.read())

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()

    root.fill((100, 50, 50))
    anime.blit(root, (100, 50))
    pygame.display.update()

如何加载声音文件而不引发此类错误？什么是“seek”？

我在Python3.6上也遇到了这个错误

我猜

pygame.mixer.music.load

会调用

zippie

上的

seek

方法，这是一个

从python 3.7

ZipExtFile

中，对象现在有了一个seek方法。我认为，如果您升级到python 3.7.2或更高版本，那么您的错误应该会消失。

尝试替换

pygame.mixer.music.load(zora)

与

这对我在Python3.6上使用

h5py.File（）

我猜这与

pygame..load（）

的问题是一样的

编辑：
我现在意识到，当您加载图像时，上述解决方案已经存在于您的代码中：

with ZipFile("spam.zip", 'r') as archive:
    mcimg = archive.read('a.png', pwd=b'onlyforthedev')
    mc = pygame.image.load(BytesIO(mcimg))

因此，为了实现一致性，您可以通过类似的方式

加载音乐

：

with ZipFile('spam.zip') as zippie:
    zora = zippie.read('zora.mp3', pwd=b'onlyforthedev')
    pygame.mixer.music.load(BytesIO(zora))

with ZipFile('spam.zip') as zippie:
    zora = zippie.read('zora.mp3', pwd=b'onlyforthedev')
    pygame.mixer.music.load(BytesIO(zora))
