【问题描述】：

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)
    in AnimatedComponent (created by Card)

在我的代码 app.js 中。 Screens and View 方法没问题。那我该怎么办？

您找到解决方案了吗？
你能把代码贴出来

【解决方案1】：

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：

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

现在是正确的：

从'/modules/my-module.js'导入myDefault；
