这是我第一次使用MongoDB，但我似乎无法解决这个问题，我使用MongoDB的朋友不知道如何使用python，所以他真的帮不了我。
这是我的代码：
import pymongo
# Replace the uri string with your MongoDB deployment's connection string.
conn_str = "mongodb+srv://sqdnoises:{mypass}@sqd.d4kjb.mongodb.net/myFirstDatabase?retryWrites=true&w=majority"
# set a 5-second connection timeout
client = pymongo.MongoClient(conn_str, serverSelectionTimeoutMS=5000)
try:
print(client.server_info())
print('nnn aka connected')
except Exception:
print("Unable to connect to the server.")
其中{mypass}是我的MongoDB密码。
我一直收到这个错误：

我该如何解决这个问题？
我在关注https://docs.mongodb.com/drivers/pymongo/
实际上，问题是dnspython试图打开/etc/resolv.conf
import dns.resolver
dns.resolver.default_resolver=dns.resolver.Resolver(configure=False)
dns.resolver.default_resolver.nameservers=['8.8.8.8']
只需将此代码添加到主代码的顶部，就足以让您克服这一障碍。。
