我正在尝试将 Flask-SocketIO 与我的 Flask 应用程序集成。
出于某种原因,我收到一个导入错误,该错误是由
from .. import socketio
我的 events.py 中的 触发的,我不知道为什么。
我将非常感谢提供的任何帮助。

app = Flask(__name__)
app.config.from_object(os.environ.get('APP_CONFIG')) # export APP_CONFIG=settings.Development
lm.init_app(app)

app.register_blueprint(main_blueprint)
socketio.init_app(app)
