Python 烧瓶超级管理员-'；模块'；对象没有属性'；文件字段'；

我尝试从文档中启动简单代码：

代码如下：

from flask import Flask
from flask.ext.superadmin import Admin

app = Flask(__name__)

admin = Admin(app)

app.run()

但出现以下错误：

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    from flask.ext.superadmin import Admin
  File "/home/un1t/workspace/dj/python/local/lib/python2.7/site-packages/flask/exthook.py", line 62, in load_module
    __import__(realname)

    class FileField(wtf.FileField):
AttributeError: 'module' object has no attribute 'FileField'

有什么问题，或者在哪里可以找到工作示例？

这是导入中的一个错误。我把它固定在我的房间里；从那里克隆，然后重试
