我有一个运行 Flask-Admin 的小项目，我已经将其 dockerised。突然之间，我无法构建项目。我已经完成了以前的提交，但无法解决问题所在。这似乎是烧瓶棉花糖的进口，但我无法获得任何关于导致它的进一步信息。
from flask import Flask, render_template, url_for, redirect
from flask_admin import Admin, AdminIndexView
from flask_sqlalchemy import SQLAlchemy
from flask_admin.contrib.sqla import ModelView
from flask_security import Security, SQLAlchemyUserDatastore, current_user, login_required, utils
from wtforms.fields import PasswordField
flask_admin import helpers as admin_helpers
from flask_marshmallow import Marshmallow
app = Flask(__name__)
app.config.from_pyfile('config.py', silent=True)
db = SQLAlchemy(app)
ma = Marshmallow(app)
回溯是：
