2 个解决方案

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 .基本上，要升级create-react-app项目，您需要做的就是将react-scripts模块更新到最新版本，并更新您的应用程序以与react-scripts任何重大更改兼容。

Run yarn upgrade --latest react-scripts , rebuild your app, and everything should more-or-less work, barring any breaking changes.运行yarn upgrade --latest react-scripts ，重建你的应用程序，一切都应该或多或少地工作，除非有任何yarn upgrade --latest react-scripts变化。

Create React App is divided into two packages: Create React App 分为两个包：

create-react-app is a global command-line utility that you use to create new projects. create-react-app是一个全局命令行实用程序，可用于创建新项目。 react-scripts is a development dependency in the generated projects (including this one). react-scripts是生成的项目（包括这个）中的一个开发依赖项。 When you run npx create-react-app my-app it automatically installs the latest version of Create React App.当您运行npx create-react-app my-app 时，它会自动安装最新版本的 Create React App。

If you've previously installed create-react-app globally via npm install -g create-react-app , please visit Getting Started to learn about current installation steps.如果您之前已通过npm install -g create-react-app全局安装 create-react-app ，请访问入门以了解当前的安装步骤。
