我该如何解决这个问题？

Answer 1

该模块似乎仅支持Python 2。 setup.py包含一个非常可疑的黑客来评估__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__

这样做的目的是找到一个以__version__开头的行，即__version__ = '0.6'，然后将其作为带有exec的动态代码执行。但是在Python 3中，不修改局部变量，因此__version__未在下一行定义。

即使您修复了这个错误，您也会遇到无数其他错误，因为该程序包根本不支持Python-3。最简单的解决方案是使用Python 2.但即便如此，我也不太确定它是否在Windows上正常运行，因为它是为mplayer / mencoder套件编写的，而且似乎非常Linux / POSIX在其代码中着迷。
