导入 Flask-Marshmallow 时出现意外的关键字参数错误

Question

我有一个小项目运行 Flask-Admin，我已经对接了它。突然之间，我无法构建项目。我已经完成了以前的提交，但无法弄清楚问题是什么。它似乎是 flask-marshmallow 的导入，但我无法获得有关导致它的原因的任何进一步信息。

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：

Traceback (most recent call last):

我刚刚从头安装了一个 Flask 项目和依赖项，但我遇到了完全相同的错误。昨天似乎已经更新了 marshmallow 包：https://pypi.python.org/pypi/marshmallow "Uploaded : 2017-03-10"

此错误已报告给开发团队：https://github.com/marshmallow-code/marshmallow/issues/597
