無需調試即可啟動React Native錯誤

Question

在命令react-native run-android啟動應用程序后，我有一個錯誤。 當我關閉遠程調試時出現錯誤。 使用調試器一切正常。

Objects are not valid as a React child (found: object with keys {$$typeof, type, key, ref, props, _owner, _store}). If you meant to render a collection of children, use an array instead or wrap the object using createFragment(object) from the React add-ons. Check the render method of `View`.

libs的版本

“react-dom”：“~15.3.2”，“react-native”：“^ 0.39.2”，

在我使用React Native的情況下，我們將這個神秘的bug拖了幾周才出現在Android版本中而沒有附加的調試器，正如你所描述的那樣

罪魁禍首是

import 'core-js'

在我們的根組件上，似乎polyfill搞砸了

只需刪除導入行並嘗試一下即可

package.json相關部分

  "react-native": "0.44.2",
  "react": "16.0.0-alpha.6",
