react-native 博览会问题 : check method of `SceneView`

Question

我不明白为什么我的代码不能运行其他设备，而我的代码在我的旧设备中检查正常。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)

在我的代码 app.js 中。 Screens and View 方法没问题。那么我必须做什么？

不确定我的问题，但是当我以错误的方式导入模块时出现类似的错误，以下是错误的:

import {myDefault} from '/modules/my-module.js';

现在是正确的:

import myDefault from '/modules/my-module.js';
