npm 错误！代码 ERESOLVE npm 错误！ ERESOLVE 无法解决。当我运行 npm install 时

Question

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

npm ERR! ERESOLVE could not resolve

即使我运行

npm install --legacy-peer-deps

我仍然遇到同样的错误。请问可能是什么问题？

这是我的 package.json 文件中的内容：

}

  "version": "1.0.0",
  "description": "",
  "keywords": [],

}

Answer 1

错误告诉您

支持

typescript@^3.2.1

（即 TypeScript >=3.2.1，<4) as a peer dependency.

您的开发依赖项中包含 TypeScript 4（不是 3.2.x），该版本的反应脚本不支持该版本，因此会出现解析错误。

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

该版本声明支持 TypeScript 4。

Answer 2

解决方案是更新到最新版本的react-scripts。

由于某种原因，运行
npm update

 无法解决该错误，因此我手动重新安装（安装最新版本）。

奔跑吧
npm remove react-scripts 然后运行
npm install react-scripts
