我有一个 Flask Web 应用程序，但当我从我自己的应用程序导入模块时，出现模块未找到错误：
Traceback (most recent call last):
File "<frozen runpy>", line 198, in _run_module_as_main
File "<frozen runpy>", line 88, in _run_code
File "/Users/joey/projects/app/app/__main__.py", line 1, in <module>
from app import serve
ModuleNotFoundError: No module named 'app'
这里出了什么问题？我的__main__.py
:
from app import serve
serve()
我的__init__.py
：
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
app = Flask(__name__)
class Config(object):
UPLOAD_DIRECTORY = app.root_path + "/uploads/"
SQLALCHEMY_DATABASE_URI = "postgresql:///app_db"
SECRET_KEY = "secret key"
app.config.from_object(Config)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
from .routes import home_page, download_page, upload_page, favicon_page
app.register_blueprint(home_page)
app.register_blueprint(download_page)
app.register_blueprint(upload_page, url_prefix="/upload")
app.register_blueprint(favicon_page)
import app.routes as routes
import app.models as models
def serve():
return app.run(host="0.0.0.0", port=1212, debug=True)
还有我的文件树：

我在这里做错了什么吗？我将不胜感激任何帮助。感谢您查看这个问题。
python app
一样运行应用程序模块，
app/将被添加到
sys.path并成为您的导入基础。因此，您必须从导入中删除
app
。您的代码也必须从
__init__.py
中移出。一般来说，只有模块初始化代码应该放在那里。在你的情况下，你可以
import __init__，但这不是最佳实践。
