我该如何解决这个问题？

Answer 1

该模块似乎只支持 Python 2。 setup.py 包含一个非常可疑的 hack 来评估 __version__ 变量：

def get_version(filename):
    """Extract __version__ from file by parsing it."""
    with open(filename) as fp:
        for line in fp:
            if line.startswith('__version__'):
                exec(line)
                return __version__

它的作用是找到以__version__开头的行，即__version__ = '0.6'，然后用exec作为动态代码执行，这样就可以了。然而在 Python 3 中，这不修改局部变量，因此__version__ 没有在下一行定义。

即使您修复了此错误，您也会遇到无数其他错误，因为该软件包根本不支持 Python-3。最简单的解决方案是使用 Python 2。但即便如此，我也不太确定这是否在 Windows 上正常工作，因为它是为 mplayer/mencoder 套件编写的，并且似乎非常注重 Linux/POSIX代码。
