React-native中的选择器

Question

刚开始学习React-native。我在选择器组件上卡住了。选择器在react-native": "0.68.2

上不工作我已经安装了——>@react-native-picker/picker进口——比;import {Picker} from '@react-native-picker/Picker ';

但是仍然得到错误信息@react-native-picker/picker无法在项目或这些目录中找到:node_modules ..node_modules

尝试了一个简单的程序来列出语言，但不工作!

class testingPicker extends Component {
state = {
language:'a'
}
render(){
return(
<View>
<Picker 
style={{width:'100%'}}

>
{/* Adding options to picker */}
<Picker.Item label="A" value="a"/>
<Picker.Item label="B" value="b"/>
</Picker>
</View>
)
}
}
export default testingPicker;
