npm WARN jest-react-native@17.0.0需要一个whowg-fetch@^1.0.0的对等方但没有安装

Question

当我尝试在ReactNative项目中运行npm install时，我收到此错误。为了解决这个问题，我尝试安装whatwg-fetch@^1.0.0但是同样的错误。

UNMET PEER DEPENDENCY whatwg-fetch@2.0.1

npm WARN jest-react-native@17.0.0 requires a peer of whatwg-fetch@^1.0.0 but none was installed.
npm ERR! code 1

您需要手动安装缺少的对等依赖项 max = list[0]; for (int i = 1; i < num; i++) { if (list[i] > max){ max = list[i]; } }
