如何解决Flask RuntimeError：没有设置图像的目的地？

开发过程中遇到Flask RuntimeError：没有设置图像的目的地的问题如何解决？下面主要结合日常开发的经验，给出你关于Flask RuntimeError：没有设置图像的目的地的解决方法建议，希望对你解决Flask RuntimeError：没有设置图像的目的地有所启发或帮助；

我在运行flask应用程序时遇到以下错误，并且在我将应用程序从window迁移到linux后开始出现这个问题，在windows 10上flask工作正常。我已经安装了所有依赖项，但在我看来存在一些配置错误，因此请提供建议。

以下是错误信息。
