导入 react-native 社区选择器时出错

Question

I'm new to react-native, since I'm using Expo and I had to install react-native community picker, I used the following command to install:

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

After that I import it like this:

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

But I get the following error:

While trying to resolve module `@react-native-community/picker` from file `C:\xampp\htdocs\secondtry\screens\HomeScreen3.js`, the package `C:\xampp\htdocs\secondtry\node_modules\@react-native-community\picker\package.json` was successfully found. 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:
