Python 我得到了一个“答案”；运行时错误：在请求上下文之外工作。”；当我实现您的登录时

我正在尝试创建一个在google应用程序引擎上运行的web应用程序。我正在尝试使用Flask登录实现身份验证。 当我运行应用程序时，我会得到如下所述的错误消息

我已经安装了Flask Login和所有其他库

如图所示，我的所有第三方库都位于项目文件夹中。

如果您需要更多信息，请告诉我

请帮帮我。这让我快发疯了

最后，我终于找到了问题所在。问题在于我如何处理lib文件夹中的第三方包

我通过添加_init__.py将lib文件夹添加到一个包中。我打电话给lib.flask导入flask。但是，flask登录模块导入flask而不是lib.flask。这就是为什么当flask登录的模块调用会话变量时，它们从flask模块而不是lib.flask中获取该变量。因此，这是断章取义的。 解决方案是从lib文件夹中删除_uinit__uuu.py。在搜索中添加lib文件夹，我已经通过添加sys.path.insert（1，os.path.join（os.path.abspath（'.'），'lib'））完成了这项工作。

如果您正在使用PyCharm，它将显示导入烧瓶的未找到错误。如果代码正常，则可以忽略错误
