我试图使用neo4j-driver将Django连接到Neo4j，但我收到安全性错误。
错误： - neo4j.exceptions.SecurityError: Failed to establish secure connection to '[SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:600)'
Python版本3.4.3 IN MACOSX
我的依赖
django1.9
neo4j-driver==1.4.0
CODE Views.py
from django.shortcuts import render
# Create your views here.
from neo4j.v1 import GraphDatabase,basic_auth
from django.conf import settings
from django.db import IntegrityError
from django.views.decorators.cache import cache_page
from django.http import HttpResponse
from django.contrib import messages
from django.http import HttpResponse, HttpResponseRedirect, JsonResponse,Http404
from django.http import StreamingHttpResponse
from django.shortcuts import render_to_response
from django.shortcuts import render
from django.template import RequestContext
from django.views.decorators.csrf import csrf_exempt
from django import template
uri = "bolt://localhost:7474"
driver = GraphDatabase.driver(uri, auth=("neo4j", "password"))
def friends(request):
name = "Cameron Crowe"
with driver.session() as session:
with session.begin_transaction() as tx:
for record in tx.run("MATCH (a:Person)-[:PRODUCED]->(f) "
"WHERE a.name = {name} "
"RETURN f.title", name=name):
print(record["f.title"])
return render(request, "friends.html")
错误
The above exception was the direct cause of the following exception:

感谢Rishabh撰写问题的解决方案。
我后来意识到端口号7474用于http协议以供ssl使用。
我已将网址格式1010更改为uri = "bolt://localhost:7474"
像魅力一样工作!!

浏览器显示端口9987，我在使用此端口时遇到异常。当我将python中的端口更改为7687
时，它工作正常答案 2 :(得分：0)
这是在Github issue here中报告的。以下是否适用于您？
pip uninstall neo4j-driver echo "deb http://httpredir.debian.org/debian/ jessie-backports main" >> /etc/apt/sources.list && apt update && apt install -y -t jessie-backports openssl
pip install neo4j-driver
