Question

我找到flask-jquery-ajax-example，我尝试使用最新的库版本运行它：

$ pip install flask flask-wtf wtforms
$ pip install -e ./

但是，在启动脚本时，我得到了 ImportError：没有名为flask.ext.wtf.SelectField 的模块：

$ python bin/runserver.py
Traceback (most recent call last):

ImportError: No module named flask.ext.wtf.SelectField

SelectField是否被新方法取代？

Answer 1

该教程在大约2年内没有更新。 Flask-WTF dropped support for field imports几个版本之前。您需要直接从WTForms导入它们。

from wtforms import SelectField

没有名为flask.ext.wtf.SelectField的模块
