我該如何解決這個問題？

Answer 1

該模塊似乎只支持Python 2。該setup.py包含一個非常可疑的黑客評價__version__變量：

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__ 

這裏做的事情是要找到與__version__，即__version__ = '0.6'開始的行，然後用exec，其工作執行它作爲動態代碼。但是在Python 3中，不會修改本地變量，因此__version__未在下一行中定義。

即使您修復了這個錯誤，您也遇到了無數其他人，因爲該軟件包根本就不是Python-3。最簡單的解決方案是使用Python 2.但即使如此，我也不太確定它是否適用於Windows，因爲它是爲mplayer/mencoder套件編寫的，而且它的代碼似乎非常注重Linux/POSIX。
