react-native – 在没有调试的情况下启动时出现React Native错误

2023年6月5日 202次阅读

在命令react-native run-
android启动应用程序后,我有一个错误.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`.

libs的版本

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

最佳答案 在我使用React Native的情况下,我们将这个神秘的bug拖了几周才出现在Android版本中而没有附加的调试器,正如你所描述的那样

罪魁祸首是

导入’core-js’

在我们的根组件上,似乎polyfill搞砸了

只需删除导入行并尝试一下即可

package.json的相关部分

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