【问题描述】：

我该怎么办？我收到这个错误。我想为 FLAC 添加一些标签。 我搜索但我没有找到任何东西。请帮帮我。

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

    datum = block.write()

    f.write(self.data)
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()

【参考方案1】：

我相信错误就在这里：

pic.data = "music.jpg"

您正在尝试将图片的图像数据设置为字符串。我猜您想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()

下面是an example in the Mutagen API reference。
