node.js - 将 Expo 升级到 SDK 40，解决 undefined@undefined 时无法安装包

Question

我现在使用的是 Expo SDK 37，需要更新到目标 Android 29。在我运行 expo upgrade、删除 Node 模块并运行 npm install 后，我得到了这个:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: undefined@undefined
npm ERR! Found: react-native@0.63.2
npm ERR! node_modules/react-native
npm ERR!   react-native@"https://github.com/expo/react-native/archive/sdk-40.0.1.tar.gz" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer react-native@"^0.49.1" from react-native-deck-swiper@1.6.7
npm ERR! node_modules/react-native-deck-swiper

npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

所以我无法安装我的包。我不确定解析 undefined@undefined 是什么意思。如何修复这些错误？

我的 package.json 看起来像这样:

看起来您正在使用 npm 7。npm 7 于 2020 年 10 月发布，并围绕 peerDependencies 的行为引入了重大更改，因此它不适用于之前发布的 Node 生态系统中的许多项目。我建议使用 npm 6 或 yarn classic。
