运行我的应用程序时使用 python manage.py run -h 0.0.0.0 很好用。
这就是 manage.py 我用来创建 flask 组的文件。

from flask.cli import FlaskGroup

from myapp import create_app

# create a flask app

app = create_app()
cli = FlaskGroup(create_app=create_app)

if __name__ == '__main__':
    cli()

我的 __init__.py 将create\u app函数传递给flaskgroup的文件：

from flask import Flask

def create_app():
    """Create a Flask application

    Returns:
        Flask: the Flask application
    """

    # instantiate the app
    app = Flask(__name__)

    # register blueprints
    from myapp.views import main_blueprint

    app.register_blueprint(main_blueprint)

    # shell context for flask cli
    app.shell_context_processor({"app": app})

    return app

如果我试着用gunicorn wsgi.py 文件：

from manage import cli

if __name__ == '__main__':
    cli.run()

那就跑吧 gunicorn 然后提出请求，我得到这个错误，我不知道如何解决。

gunicorn --bind=0.0.0.0:5000 wsgi:cli                                           ──(Thu,Apr08)─┘

对这个错误的帮助将是巨大的。谢谢！
