react-native博览会问题：“ SceneView”的检查方法

Question

我不明白为什么我的代码无法在其他设备上运行，而我的代码在旧设备中被检查为正常。这是通知：

Invariant Violation: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.

Check the render method of `SceneView`.

This error is located at:
    in SceneView (created by StackViewLayout)
    in RCTView (created by View)
    in View (created by AnimatedComponent)
    in AnimatedComponent (created by Card)
    in Card (created by Container)

在我的代码app.js中。屏幕和视图的方法还可以。那我该怎么办？

不确定我的问题，但是以错误的方式导入模块时出现类似的错误，下面是错误的：

  

从'/modules/my-module.js'导入{myDefault};

现在是正确的：

  

从'/modules/my-module.js'导入myDefault;
