Question

我正在按照本教程学习如何使用stormpath和本教程（https://stormpath.com/blog/build-a-flask-app-in-30-minutes）在flask上创建一个缺少此功能的用户身份验证系统;在试用它并感受到内容之后，我尝试通过设置

来调查启用注册

app.config['STORMPATH_ENABLE_REGISTRATION'] = False

在flaskr.py文件中

为True;启用默认的stormpath注册页面，但在连接到localhost / register时，它给了我这个长时间的错误，我无法做出正面或反面：

我完全不知道出了什么问题，我在文档或类似错误中找不到任何内容。

当你遇到Python堆栈跟踪时，从底部开始并逐步完成：

form.py

这表示form.py中的函数使用不正确。由于File "C:\Python35-32\lib\site-packages\flask_stormpath\views.py", line 39, in register form = RegistrationForm(config=current_app.config) File "C:\Python35-32\lib\site-packages\wtforms\form.py", line 212, in __call__ return type.__call__(cls, *args, **kwargs) File "C:\Python35-32\lib\site-packages\flask_stormpath\forms.py", line 40, in __init__ **kwargs) File "C:\Python35-32\lib\site-packages\flask_wtf\form.py", line 158, in __init__ super(Form, self).__init__(*args, **kwargs) TypeError: __init__() takes from 1 to 2 positional arguments but 7 were given是flask-wtf的一部分，你不太可能修改它（我希望！），继续上去：

RegistrationForm(config=current_app.config)

此处候选人的可能性更大：views.py第39行的config=current_app.config被错误地调用或者WTForms没有预料到的方式。它可能是views.py。

如果可能的话，从表单 s .py导入应用程序配置中的变量，并在{{1}}中使用之前进行表单配置。

发生错误是因为您使用的是Flask-WTF版本0.14或更高版本（此版本中引入了一些与先前版本不兼容的更改）。这解释了为什么stacktrace提到了pNode := pDocument.DocumentElement;：

flask_wtf

此问题已在stormpath-flask的File "C:\Python35-32\lib\site-packages\flask_wtf\form.py", line 158, in __init__ super(Form, self).__init__(*args, **kwargs) TypeError: __init__() takes from 1 to 2 positional arguments but 7 were given分支中修复，但尚未发布。如果您不能等待正式发布，请查看详细更改in this pull request。要解决此问题，只需在本地flask-stormpath安装中实现pull请求中develop中显示的更改。

所以在你的情况下，你会：

flask_stormpath/forms.py cd C:\Python35-32\lib\site-packages\flask_stormpath 目录（我们根据你收到的堆栈跟踪知道这个。）
打开forms.py并进行拉取请求中显示的更改上面链接
