Mimetypes.init（）错误时

Question

EDIT：问题通过贯通孔C解决：\ Python27 \ LIB \ mimetypes.py和添加代码缺点try块：

## Begin to line 245 :  
try: 
    ctype = _winreg.EnumKey(mimedb, i) 
except EnvironmentError: 
    break 
try: 
    ctype = ctype.encode(default_encoding) # omit in 3.x! 
except UnicodeEncodeError: 
    pass 

## Here, add the universal Exception missing. 
except Exception: 
    pass 

else: 
    yield ctype 

我从3天前开始搜索，但解决这个问题对我来说太难了。我不明白问题在哪里。

我试图通过使用GitHub，PowerShell 3等来安装我的软件包。所有这些都不起作用。除了PIP至极似乎有一个小错误...

当我试图通过使用PIP安装tweepy，这个错误追加：

你能解释一下我请，如何repear这个？

在此先感谢， SkyzohKey。

看起来你有一个在注册表中导致问题的mimetype。您可以运行下面的脚本要弄清楚它是哪一个：

import _winreg 


def find_funky_mimetype(): 
    default_encoding = sys.getdefaultencoding() 
    with _winreg.OpenKey(_winreg.HKEY_CLASSES_ROOT, 
         r'MIME\Database\Content Type') as mimedb: 
     i = 0 
     while 1: 
      try: 
       ctype = _winreg.EnumKey(mimedb, i) 
      except EnvironmentError: 
       break 
      print 'testing:', `ctype`, 
      try: 
       ctype = ctype.encode(default_encoding) # omit in 3.x! 
      except UnicodeEncodeError: 
       print 'expected failure' 
      except Exception as e: 
       print 'unexpected failure:', e 
      else: 
       print 'ok.' 
      i += 1 


if __name__ == "__main__": 
    find_funky_mimetype() 

你应该做些什么完全取决于你，你感到舒服（例如移除从注册表有问题的MIME类型或添加除了`c：\ Python27 \ lib \ mimetypes.py'的第252行外，其他都是通用的，类似于我上面所做的）。
