Question

我在命令react-native run-android启动应用程序后发现了一个错误。当我关闭远程调试时出现错误。使用调试器，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`.

版本的libs

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

在我使用React Native的情况下，我们将这个神秘的bug拖了几个星期才出现在Android版本中而没有你所描述的附加调试器

罪魁祸首是

import 'core-js'

在我们的根组件上，似乎 polyfill 搞得一团糟

只需删除导入行并试一试

package.json

的相关部分

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

无需调试即可启动React Native错误
