导入反应本地社区选择器时出错

Question

我是React-native的新手，因为我正在使用Expo，并且必须安装react-native社区选择器，所以我使用以下命令进行安装：

npm install @react-native-community/picker --save

之后，我像这样导入它：

import {Picker} from '@react-native-community/picker';

但是出现以下错误：

However, this package itself specifies a `main` module field that could not be resolved (`C:\xampp\htdocs\secondtry\node_modules\@react-native-community\picker\js\index.js`. Indeed, none of these files exist:
