python3.4找不到OpenSSL

Question

我尝试在python3.4（windows7）中使用WebSockets 这是一个测试代码：

from twisted.internet import reactor
from autobahn.twisted.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS
import json

class ClientProtocol(WebSocketClientProtocol):
    def onConnect(self, response):
        print("Server connected: {0}".format(response.peer))
    def initMessage(self):
        message_data = [{"type": "subscribe", "product_id": "BTC-USD"}]
        message_json = json.dumps(message_data)
        print("sendMessage: " + message_json)
        self.sendMessage(message_json)
    def onOpen(self):
        print("onOpen calls initMessage()")
        self.initMessage()
    def onMessage(self, msg, binary):
        print("Got echo: " + msg)
    def onClose(self, wasClean, code, reason):
        print("WebSocket connection closed: {0}".format(reason))

if __name__ == '__main__':
    factory = WebSocketClientFactory("wss://ws-feed.exchange.coinbase.com")
    factory.protocol = ClientProtocol
    connectWS(factory)
    reactor.run()

启动时出现错误：

但当我试图安装OpenSSL时，出现了一个错误：

F:\python>easy_install openssl
Searching for openssl
Reading https://pypi.python.org/simple/openssl/
Couldn't find index page for 'openssl' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
No local packages or download links found for openssl
error: Could not find suitable distribution for Requirement.parse('openssl')
