ReactNative问题: warning react-native > create-react-class > fbjs > core-js@1.2.7: core-js@

ReactNative问题:

warning react-native > create-react-class > fbjs > core-js@1.2.7: core-js@<2.6.8 is no longer maintained. Please, upgrade to core-js@3 or at least to actual version of core-js@2

处理:

下载并保存core-js警告消息中请求的模块版本：

npm install --save core-js@^3

这将更新项目的core-js依赖关系，react-native以使用^3.x.x仍在积极维护的版本
