npm 錯誤。 代碼 ERESOLVE npm 錯誤！ ERESOLVE 無法解析。 當我運行 npm 安裝時

Question

當我運行“npm install”從克隆的存儲庫安裝依賴項時，我從終端收到以下錯誤。 我用 windows 10

npm ERR! ERESOLVE could not resolve

npm ERR! While resolving: react-scripts@4.0.0

即使當我運行npm install --legacy-peer-deps時，我仍然會遇到同樣的錯誤。 請問什么可能是錯的？

這是我的 package.json 文件中的內容：

  "version": "1.0.0",
  "description": "",

}

Answer 1

該錯誤告訴您react-scripts@4.0.0支持typescript@^3.2.1 （即 TypeScript >=3.2.1, <4）作為對等依賴項。

您的開發依賴項中有 TypeScript 4（不是 3.2.x），該版本的 react-scripts 不支持，因此解析錯誤。

react-scripts 的當前版本是 5.0.1 ，所以我建議將 react-scripts 升級到該版本（只需將 package.json 中的"4.0.0"更改為"5.0.1" ）並重試，因為那版本聲明支持 TypeScript 4 。
