我正在设置一个新组件“ SearchResultListItem”,由于某种原因,我得到一个指向“ SearchResult”的错误,并且不清楚我的代码有什么问题。

这是我的依赖项:

"dependencies": {
    "bugsnag-react-native": "^2.15.0",
    "lodash": "^4.17.11",
    "mobx": "3.4.0",

现在是SearchResult组件。

export default SearchResultListItem

我希望获得产品的输出,但是出现错误消息:

Invariant Violation:Element type is invalid:expected a string..
