推荐答案
下载并保存警告消息中请求的 core-js
模块的版本:
Download and save the version of the core-js
module which is requested within your warning message:
npm install --save core-js@^3
这将更新您的 react-native
项目的 core-js
依赖项以使用仍在积极使用的版本 ^3.xx
保持.
This will update the core-js
dependency for your react-native
project to use version ^3.x.x
which is still being actively maintained.
