我从 React Native (Expo) 开始了我的故事。有一天我需要安装 datetimepicker。不幸的是，我做错了什么。我试图自己面对这个问题。我删除了 node_modeles 目录和 package.lock.json。当我尝试 npm install 时，出现以下错误：
错误提示

我知道这是依赖版本错误的问题，但我不知道如何修复它:( 那是我的 package.json。
更新package.json

我怎样才能让它重新工作？
我创建了一个新项目，并通过 expo install 安装了所有依赖项，没有 react-native-modal-datetime-picker。我已经复制并依赖于我的原始项目。当我使用 npm install 时，我的项目安装正确并显示以下消息：
