Python tornado - [Errno 113]没有主机路线

Question

我在龙卷风框架中有错误，我根本无法找到任何解决方案。

任何人都有类似的问题或知道这是什么？

WARNING:tornado.general:error on read
Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/tornado/iostream.py", line 644, in _handle_read
    pos = self._read_to_buffer_loop()
  File "/usr/local/lib/python2.6/dist-packages/tornado/iostream.py", line 614, in _read_to_buffer_loop
    if self._read_to_buffer() == 0:
  File "/usr/local/lib/python2.6/dist-packages/tornado/iostream.py", line 726, in _read_to_buffer
    chunk = self.read_from_fd()
  File "/usr/local/lib/python2.6/dist-packages/tornado/iostream.py", line 1005, in read_from_fd
    chunk = self.socket.recv(self.read_chunk_size)
error: [Errno 113] No route to host

我使用Python 2.6.6，我应该将其升级到2.7.9吗？
