Python 访问烧瓶应用程序'；s配置给出了；模块对象没有属性“uu getitem”；

我正在尝试对我的flask应用程序实施电子邮件身份验证，用户必须在完成在线注册过程后确认其电子邮件地址。我猜这可能是我在app.py中设置配置的方式，或者我应该修改我的config.py？有什么想法吗

这是我的app.py

....
import config

app = Flask(__name__)

# Import configuration
app.config.from_object(config.DevelopmentConfig)

# Initialize extensions
lm = LoginManager()
lm.session_protection = 'strong'
lm.init_app(app)
bootstrap = Bootstrap(app)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
manager = Manager(app)
manager.add_command('db', MigrateCommand)
moment = Moment(app)
mail = Mail(app)
......

这是我的代币

from itsdangerous import URLSafeTimedSerializer
import app


def generate_confirmation_token(email):
    serializer = URLSafeTimedSerializer(app.config['SECRET_KEY'])
    return serializer.dumps(email, salt=app.config['SECRET_PASSWORD_SALT'])

def confirm_token(token, expiration=3600):
    serializer = URLSafeTimedSerializer(app.config['SECRET_KEY'])
    try:
        email = serializer.loads(token, salt=app.config['SECRET_PASSWORD_SALT'], max_age=expiration)
    except:
        return False
    return email

这是flask debug生成的错误日志
