flask-admin TypeError: Невозможно скомпилировать узлы без шаблонов

/ 21 февраля 2019

Я слежу за обучением на youtube по работе с flask-admin.Прямо сейчас я просто пытаюсь заставить его работать в rout.py, чтобы увидеть, как он работает (я также пробовал модели, и каждый раз происходит сбой).

Вот мой код 

from flask_login import UserMixin
from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(20))
admin = Admin(app)
admin.add_view(ModelView(User, db.session))

когда я делаю http://127.0.0.1:5000/admin/ в своем браузере, я получаю сообщение об ошибке 

builtins.TypeError
TypeError: Can't compile non template nodes

Последние 3 часа я потратил на то, чтобы выяснить, что происходит, но ничего не происходитчувствую, и я не могу найти нигде подобных проблем.
