導入Flask WTF表單時導入錯誤

我看不到我要出錯的地方。我安裝了最新的WTF表單，但仍然出現此錯誤。導入Flask WTF表單時導入錯誤

方法：

from flask.ext.wtf import Form 
from wtforms import PasswordField, validators, fields 
from wtforms.fields import TextField, BooleanField 
from wtforms.validators import Required, Email, EqualTo

結果：

你是如何安裝的燒瓶跆拳道改變了嗎？你的代碼很好，這可能是一個環境問題。 – iurisilvio

你可以發佈'ls/usr/local/lib/python3.3/dist-packages/flask'和'ls /usr/local/lib/python3.3/dist-packages/ | grep wtf'？ – brunsgaard

按照official quickstart，flask.ext.wtf應該flask_wtf。

所以，你必須導入爲：

from flask_wtf import FlaskForm

至少我有，我從PIP安裝。

試過，以及那不工作 – Lorbat

如果你是你唱一個腳本來運行你的代碼（例如run.py），檢查你正在運行正確的python版本：「which python」或「which python3」。如果你使用的是virtualenv，請確保你運行了它。 – Inyoka

看起來你只安裝了wtforms，不Flask-WTF擴展。

要安裝Flask-WTF：pip install flask-wtf

我已經安裝Flask-WTF – Lorbat

請使用

from flask_wtf import Form 

from wtforms import TextField, BooleanField,IntegerField 
from wtforms.validators import Required

這已自V0.8
