[英]React Native AsyncStorage=> TypeError: Cannot read property 'login' of undefined
[英]React-Native AsyncStorage: TypeError: Cannot read property 'setItem' of undefined
我正在学习 react-native 并尝试使用
AsyncStorage<\/code> 。
我正在使用此代码来存储数据:
_storeData = async (token) => {
console.log("store token");
console.log(token);
try {
await AsyncStorage.setItem('token', token);
} catch (error) {
// Error saving data
console.log(error);
}
}

调用它: this._storeData(res.token);
但这给了我这个错误:

有人可以帮我解决我做错的事情吗? 谢谢

我面临着同样的问题。
如果你正在使用
然后按照https:\/\/react-native-async-storage.github.io\/async-storage\/docs\/install\/<\/a>在您的项目中安装 AsyncStorage。
安装和链接完成后,将其导入您的项目:
import AsyncStorage from '@react-native-async-storage/async-storage';
