我该如何解决这个问题？

Answer 1

该模块似乎只支持Python 2。该setup.py包含一个非常可疑的黑客评价__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__ 

这里做的事情是要找到与__version__，即__version__ = '0.6'开始的行，然后用exec，其工作执行它作为动态代码。但是在Python 3中，不会修改本地变量，因此__version__未在下一行中定义。

即使您修复了这个错误，您也遇到了无数其他人，因为该软件包根本就不是Python-3。最简单的解决方案是使用Python 2.但即使如此，我也不太确定它是否适用于Windows，因为它是为mplayer/mencoder套件编写的，而且它的代码似乎非常注重Linux/POSIX。
