OperationalError：（sqlite3.OperationalError）no such table：user

我完全不熟悉烧瓶和Web开发。我需要的是使用蒸汽ID登录到一个网站。我做它，因为它说here，但出现以下错误：OperationalError：（sqlite3.OperationalError）no such table：user

OperationalError: (sqlite3.OperationalError) no such table: user

它似乎正确地打开蒸汽网站，但是当我按登录它打破。那么，我的错误是什么？任何帮助表示赞赏。代码：

您需要在运行你的应用程序之前运行db.create_all()。这将创建您的模型在数据库中描述的所有表格。

如果您是烧瓶新手，可以按照快速入门指导here
