TypeError:需要一个类似字节的对象，而不是'str‘

Question

我该怎么办？我得到了这个错误。我想为FLAC添加一些标签。我找了一遍，但什么也没找到。请帮帮我。

    Traceback (most recent call last):
  File "indir.py", line 50, in <module>
    audio.save()

TypeError: a bytes-like object is required, not 'str'

我的代码：

audio = FLAC("music.flac")
audio['artist'] = sarki.artist.name
audio['title'] = sarki.name
pic = Picture()
pic.type = id3.PictureType.COVER_FRONT
pic.width = 640
pic.height = 640
pic.mime = 'image/jpeg'
pic.data = "music.jpg"

audio.add_picture(pic)
audio.save()

Answer 1

我认为错误在这里：

pic.data = "music.jpg"

您正在尝试将图片的图像数据设置为字符串。我猜您希望将图像数据设置为文件music.jpg的内容。如果是这样，请尝试将此行替换为以下两行：

with open("music.jpg", "rb") as f:
    pic.data = f.read()

这是在an example in the Mutagen API reference之后。
