python 3.6 w w 1.11.1 几个小时前，我的wagtail项目停止成功启动。它失败了：
from wagtail.wagtailadmin import edit_handlers
print(dir(edit_handlers))
class Article(Page):
html = RichTextField()
content_panels = Page.content_panels + [
edit_handlers.FieldPanel('html', classname="full"),
edit_handlers.InlinePanel('gallery', label="Carousel items", classname='ArticleImage'),
]
有错误
AttributeError: module 'wagtail.wagtailadmin.edit_handlers' has no attribute 'FieldPanel'
之后我决定确保它不是我的环境错误和配置的docker文件：
FROM python:latest
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
RUN pip install wagtail
ADD . /code/
在该docker容器未成功启动之后（引发相同的错误）
我根据文档编写了这段代码： http://docs.wagtail.io/en/v1.9/reference/pages/panels.html
如何解决？
感谢名单
UPD
完整日志:(第一行是print(dir(edit_handlers))的输出）
