通过apt(python 2.5,simplejson等)安装必要的软件包后,当我尝试运行演示时出现错误。


: Request instance has no attribute 'responseHeaders'
/usr/lib/python2.5/site-packages/tornado/web.py, line 404 in flush
402    for k,v in self._generate_headers():
403      if isinstance(v, list):
404        self.request.responseHeaders.setRawHeaders(k, v)
405      else:
Self
request 
twisted.web.server.Request instance @ 0x85da24c 
Locals
self    
k   'Set-Cookie'
v   
List instance @ 0x85da46c

以下是安装必要软件包的证据

似乎没有太多人从朋友的朋友那里尝试过这个龙卷风的事情。任何人都有任何建议/提示,以帮助我启动和运行它?

我的印象龙卷风并不依赖于扭曲。你试过“官方”版本吗?第404行完全不同。

http://github.com/facebook/tornado/blob/master/tornado/web.py

def flush(self, include_footers=False):
    """Flushes the current output buffer to the nextwork."""
    if self.application._wsgi:
        raise Exception("WSGI applications do not support flush()") #line 404
    if not self._headers_written:
        self._headers_written = True
        headers = self._generate_headers()
    else:
        headers = ""

除此之外,我会尝试安装扭曲,看看会发生什么
