AttributeError: модуль 'django .db.models' не имеет атрибута 'RichTextField'

Я новичок в трясогузке и следую как официальным, так и учебным пособиям по YouTube (все-таки пропускаются инструкции по установке libjpeg и zlib, но когда я пытался, там говорится, что они включены в Pillow); Работает на windows10, используя последнюю python, последнюю трясогузку, последнюю версию django; Застрял на первом месте, все еще получая ту же проблему при запуске makemigrations или migrate или runserver: 

File "C:\Users\TalkyWalky\Desktop\Workspace\bloggyblog\home\models.py", line 14, in 
HomePage
    banner_subtitle = models.RichTextField(features=["bold", "italic"])
AttributeError: module 'django.db.models' has no attribute 'RichTextField'

вот мои модели.py:

    from django.db import models

from wagtail.core.models import Page
from wagtail.core.fields import RichTextField
from wagtail.admin.edit_handlers import FieldPanel

class HomePage(Page):
    """Homepage model."""
    body = RichTextField(blank=True)
    templates = "templates/home/home_page.html"
    max_count = 1

    banner_title = models.CharField('Body', blank=True)
    banner_subtitle = models.RichTextField(features=["bold", "italic"])
    banner_image = models.ForeignKey(features=
        "wagtailImages.Image",
        null=False,
        blank=False,
        on_delete=models.SET_NULL,
        related_name="+"
    )
    banner_cta = models.ForeignKey(
        "wagtailcore.Page",
    )

    content_panels = Page.content_panels + [
        FieldPanel("banner_title"),

    ]
    class Meta:
        verbose_name = "HomePage"
        verbose_name_plural = "HomePages"

И вот полный возвратный след: 

Traceback (most recent call last):

А вот что происходит, когда я запускаю wagtail updatemodulepaths:

Вы не должны писать <s>models.</s>RichTextField, так как на самом деле такого класса не существует в модуле django.db.models. Вы должны просто использовать RichTextField, поскольку вы импортировали его: 

from django.db import models

from wagtail.core.models import Page
from wagtail.core.fields import <b>RichTextField</b>
from wagtail.admin.edit_handlers import FieldPanel

class HomePage(Page):
    """Homepage model."""
    body = RichTextField(blank=True)
    templates = "templates/home/home_page.html"
    max_count = 1

    banner_title = models.CharField('Body', blank=True)
    # no <s>models.</s>
    banner_subtitle = <b>RichTextField(</b>features=["bold", "italic"]<b>)</b>
    banner_image = models.ForeignKey(features=
        "wagtailImages.Image",
        null=False,
        blank=False,
        on_delete=models.SET_NULL,
        related_name="+"
    )
    banner_cta = models.ForeignKey(
        "wagtailcore.Page",
    )

    content_panels = Page.content_panels + [
        FieldPanel("banner_title"),

    ]
    class Meta:
        verbose_name = "HomePage"
        verbose_name_plural = "HomePages"
...
