npm 错误。 代码 ERESOLVE npm 错误！ ERESOLVE 无法解析。 当我运行 npm 安装时

Question

当我运行“npm install”从克隆的存储库安装依赖项时，我从终端收到以下错误。 我用 windows 10

npm ERR! ERESOLVE could not resolve

npm ERR! While resolving: react-scripts@4.0.0

即使当我运行npm install --legacy-peer-deps时，我仍然会遇到同样的错误。 请问什么可能是错的？

这是我的 package.json 文件中的内容：

}

该错误告诉您react-scripts@4.0.0支持typescript@^3.2.1 （即 TypeScript >=3.2.1, <4）作为对等依赖项。

您的开发依赖项中有 TypeScript 4（不是 3.2.x），该版本的 react-scripts 不支持，因此解析错误。

react-scripts 的当前版本是 5.0.1 ，所以我建议将 react-scripts 升级到该版本（只需将 package.json 中的"4.0.0"更改为"5.0.1" ）并重试，因为那版本声明支持 TypeScript 4 。
