Question

我正在使用Pycharm和Python 3.4开发Django 1.8.4项目

我试图在shell上创建一个Model对象来测试一些东西并在执行这一行时：

song1 = Cancion.objects.create(nombre="City Lights",
                               audio_file=File(open("C:\\Users\\pablo\\Desktop\\Music\\Brian Culbertson  - Another Long Night Out (2014)\\01 - City Lights (Feat. Lee Ritenour).mp3",encoding="utf-8")))

我收到此错误：

  File "<input>", line 2, in <module>

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 21: invalid start byte

有人能告诉我命令的编码问题在哪里吗？

谢谢！

使用open这样的open('C:\\...', encoding='utf-8')函数意味着，使用utf-8编码读取我的文本文件。由于你试图读取一个mp3文件（二进制），这不起作用。

阅读方法是：open('C:\\coolSong.mp3', mode='rb')这意味着，请阅读我的旁边文件。

在此处查看关于the open function and it's modes和overview about io的真正好的解释。
