嗨，我遇到了以下代码的问题。

PS：它可以在我的本地计算机上正常工作，但面临服务器中的问题。

import geoip2.database

def get_geo_city_from_ip(ip="103.148.20.109"):

    try:
        reader = geoip2.database.Reader('GeoLite2-City.mmdb')
        response = reader.city(ip)
        city=response.city.name
        reader.close()
        return city
    except Exception as e:
        return None
a = get_geo_city_from_ip()
print("City ####",a)

错误
