python 的 EOFError: EOF when reading a line 是什么原因？

Question

在程序执行过程中，出现过如题的错误信息。

google了一些，好像是python或部署的原因，但是有这些错误信息：

   Traceback (most recent call last):

   ...

    return opener.open(url)

    return getattr(self, name)(url)

EOFError: EOF when reading a line

这是权限问题？

到底是什么问题呢？

根据楼主在评论里的回复，如果想继续使用urllib的话，可以使用FancyURLopener并且自己定义一个prompt_user_password方法。

urllib的易用性的确是经常为人所诟病.. 所以另外一个办法是，换用一个更好用的库。我推荐python-requests。用这个库就可以这么写（复制自那个链接）：

>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
>>> r.status_code
200
>>> r.headers['content-type']
'application/json; charset=utf8'
>>> r.encoding
'utf-8'
>>> r.text
u'{"type":"User"...'

安装SublimeREPL,然后编译python文件的时候，可以选择【Tools】——【sublimeREPL】——【python】——【Python – RUN current file】即可提示用户输入。应该可以解决sublime下面使用raw_input函数报错的问题。
