问题描述
我正在尝试为 React Native 和 Expo 导入 Lottie，并且我是这方面的绝对初学者。我安装了这个版本的 react-native：4.14.0
我不明白“虽然解析：undefined@undefined 是什么意思？但我想我的版本有冲突。
$ npm i --save lottie-react-native

//DEPENDENCIES from package.json:

}
解决方法
在 Expo 环境中，您必须以不同的方式安装 Lottie via：
expo install lottie-react-native
如果还没有完成，请删除 lottie-react-native 的条目并通过 expo 安装它。它应该像这样工作。
您能否将以下 Package.json 条目替换为：
"react": "16.13.1",
"react-dom": "16.13.1",
"react-native": "https://github.com/expo/react-native/archive/sdk-40.0.0.tar.gz",
我认为 React 版本与 Expo React Native 版本不兼容。
