使用Python的HTTP请求：TypeError：需要一个整数（得到类型套接字）

我在尝试通过HTTP检索资源时遇到了一个非常奇怪的错误。它似乎发生在任何HTTP客户端（尝试请求和urllib具有相同的结果）。使用Python的HTTP请求：TypeError：需要一个整数（得到类型套接字）

我的项目使用django，我使用tox和标准django命令python manage.py test运行我的测试。当我运行我的测试套件并且单元测试发出HTTP请求（例如通过requests.get('http://example.com')）时，测试失败并出现错误，测试套件一直持续到结束并挂起。我必须通过命令行手动杀死进程。

一些调查后，我把try/except块arount http请求，并得到了以下堆栈跟踪：

File "/mycomputer/python3.4/site-packages/requests/api.py", line 68, in get 
    return request('get', url, **kwargs) 
File "/mycomputer/python3.4/site-packages/requests/api.py", line 50, in request 
    response = session.request(method=method, url=url, **kwargs) 
File "/mycomputer/python3.4/site-packages/requests/sessions.py", line 464, in request 
    resp = self.send(prep, **send_kwargs) 
File "/mycomputer/python3.4/site-packages/requests/sessions.py", line 576, in send 
    r = adapter.send(request, **kwargs) 
File "/mycomputer/python3.4/site-packages/requests/adapters.py", line 370, in send 
    timeout=timeout 
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connectionpool.py", line 544, in urlopen 
    body=body, headers=headers) 
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connectionpool.py", line 349, in _make_request 
    conn.request(method, url, **httplib_request_kw) 
File "/usr/lib/python3.4/http/client.py", line 1065, in request 
    self._send_request(method, url, body, headers) 
File "/usr/lib/python3.4/http/client.py", line 1103, in _send_request 
    self.endheaders(body) 
File "/usr/lib/python3.4/http/client.py", line 1061, in endheaders 
    self._send_output(message_body) 
File "/usr/lib/python3.4/http/client.py", line 906, in _send_output 
    self.send(msg) 
File "/usr/lib/python3.4/http/client.py", line 841, in send 
    self.connect() 
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connection.py", line 155, in connect 
    conn = self._new_conn() 
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/connection.py", line 134, in _new_conn 
    (self.host, self.port), self.timeout, **extra_kw) 
File "/mycomputer/python3.4/site-packages/requests/packages/urllib3/util/connection.py", line 68, in create_connection 
    sock = socket.socket(af, socktype, proto) 
File "/usr/lib/python3.4/socket.py", line 123, in __init__ 
    _socket.socket.__init__(self, family, type, proto, fileno) 
TypeError: an integer is required (got type socket)

我真的不明白这里的问题。从命令行运行相同的东西完美地工作，所以它可能与我的项目体系结构有关。另外，在另一台计算机上运行测试套件也会以同样的方式失败。

有没有人遇到过类似的问题？我能做些什么来追踪问题？
