g：更新Django 1.10.8-> 1.11-ImportError：无法导入名称'FieldPanel'

Question

我目前正在升级我的Wagtail网站，并被卡住了。

W：1.13.4 Django：1.10.8

Site在Django 1.10.8中工作正常，但是当我尝试ImportError: cannot import name 'FieldPanel'时在1.11中抛出python manage.py runserver。

我没有任何迁移要做，并且我已经检查了我的Wagtail版本是否从1.5升级到了这一点。

我在一个名为member的应用程序中有一个自定义用户模型，并且在我的项目设置中将其声明为：

INSTALLED_APPS = [
    'home',
    'search',
    'overextends',
    'dashboard',
    'lineage',
    'gunicorn',
    'wagtail.wagtailforms',
    'wagtail.wagtailredirects',
    'wagtail.wagtailembeds',
    'wagtail.wagtailsites',
    'wagtail.wagtailusers',
    'wagtail.wagtailsnippets',
    'wagtail.wagtaildocs',
    'wagtail.wagtailimages',
    'wagtail.wagtailsearch',
    'wagtail.wagtailadmin',
    'wagtail.wagtailcore',
    'wagtail.contrib.modeladmin',

    'members',

    'modelcluster',
    'compressor',
    'taggit',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]
#lots of extra stuff here.. editted for brevity...
WAGTAIL_SITE_NAME = "mySite"
AUTH_USER_MODEL = 'members.MyUser'

这是追溯：
