AttributeError：模块'wagtail.wagtailadmin.edit_handlers'没有属性'FieldPanel'

python3.6 w 1. 1.10.1几个小时前，我的基于w based的项目停止发射成功。 它在这里失败：

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'), ] 

与错误

 AttributeError: module 'wagtail.wagtailadmin.edit_handlers' has no attribute 'FieldPanel' 

之后，我决定确保它不是我的环境和configuration的docker文件的错误：

 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/ 

之后，docker集装箱未能成功启动（引发同样的错误）

我按照文档编写了这个代码： http : //docs.wagtail.io/en/v1.9/reference/pages/panels.html

怎么解决？

感谢名单

UPD完整日志：（第一行是print(dir(edit_handlers))的输出print(dir(edit_handlers)) ）
