基本上，要升级 create-react-app 项目，您需要做的就是将反应脚本模块更新到最新版本，并更新您的应用程序以使其兼容反应脚本的任何重大更改。
Basically, to upgrade a create-react-app project, all you need to do is update the react-scripts module to the latest version and update your app to be compatible with any breaking changes in react-scripts.
运行 纱线升级-最新的反应脚本 ，重新构建您的应用，一切都应该更多-或更少的工作，除非有任何重大更改。
Run yarn upgrade --latest react-scripts, rebuild your app, and everything should more-or-less work, barring any breaking changes.
