当运行我的服务器出现以下错误时

我已经尝试运行页面背景上的脚本，但我得到了相同的错误代码，主题标签确实打印在控制台中 window，我正在尝试获取将推文存入 csv 文件以备后用。

from django.shortcuts import render_to_response
from django.http import HttpResponse
from tweepy import *


CKey = 'xxxxx'           #API Key
ConSec = 'xxxxx'         #Consumer Secret
AccTok = 'xxxxx'         #Access Token
AccTSec = 'xxxxx'        #Access Token Secret


class StdOutListener(StreamListener):

    def on_status(self, status):

        print(status.text)
        return True

    def on_error(self, status):

        print(status)


def index(request):
    try:
        listener = StdOutListener()
        auth = OAuthHandler(CKey, ConSec)
        auth.set_access_token(AccTok, AccTSec)
        stream = Stream(auth, listener)
        gimme = stream.filter(track=["lol"])
        return HttpResponse(gimme)

        #return render_to_response('index.html')
    except RuntimeError:
        pass

所以，我设法在 CSV 上捕获了数据，但是当进程运行时页面没有加载。...但是我确实得到了一个 CSV 文件，其中包含我想要的所有信息。

from django.http import HttpResponse
from tweepy import *



CKey = 'xxxxx'           #API Key
ConSec = 'xxxxx'         #Consumer Secret
AccTok = 'xxxxx'         #Access Token
AccTSec = 'xxxxx'        #Access Token Secret


class StdOutListener(StreamListener):

def on_status(self, status):
    try:

        hashdb = open("hashtag.csv", 'a')
        hashdb.write(status.text)
        hashdb.write('\n')
        hashdb.close()
    except BaseException:
        print("could not process")
def on_error(self, status_code):
    print(status_code)
    return status_code


def index(request):

    listener = StdOutListener()
    auth = OAuthHandler(CKey, ConSec)
    auth.set_access_token(AccTok, AccTSec)
    stream = Stream(auth, listener)
    gimme = stream.filter(track=["lol"])
    html = "<html><body>It is now %s.</body></html>" % gimme
    return HttpResponse(html)
