我正在尝试在 React Native 应用中设置 redux-persist。

但是我遇到了这个错误：

console.error: "redux-persist failed to create sync storage. falling back to "noop" storage

我试图在“src/redux/index.js”中将存储从 storage 更改为 AsyncStorage，但仍然遇到相同的错误：

import AsyncStorage from '@react-native-community/async-storage';

const config = {
  key: "root",
  storage: AsyncStorage // Attempted to fix it (but failed)
  // storage // old code
};

这是其他代码：

在 App.js 中：

import React, { Component } from "react";
import { Provider } from "react-redux";
import { persistStore } from "redux-persist";
import { PersistGate } from "redux-persist/es/integration/react";
import store from "@store/configureStore";
import Router from "./src/Router";

export default class ReduxWrapper extends Component {
  render() {
    const persistor = persistStore(store);
    return (
      <Provider store={store}>
        <PersistGate persistor={persistor}>
          <Router />
        </PersistGate>
      </Provider>
    );
  }
}

在 configureStore.js 中：

import { applyMiddleware, compose, createStore } from "redux";
import thunk from "redux-thunk";
import reducers from "@redux";

const middleware = [
  thunk,
  // more middleware
];

const configureStore = () => {
  let store = null;
  store = compose(applyMiddleware(...middleware))(createStore)(reducers);
  return store;
};

export default configureStore();

在 /src/redux/index.js 中

import { persistCombineReducers } from "redux-persist";
import storage from "redux-persist/es/storage";

import { reducer as NetInfoReducer } from "./NetInfoRedux";
import { reducer as UserRedux } from "./UserRedux";

const config = {
  key: "root",
  storage,
};

export default persistCombineReducers(config, {
  netInfo: NetInfoReducer,
  user: UserRedux,
}

在 Router.js 中

import React from "react";
import NetInfo from "@react-native-community/netinfo/lib/commonjs";
import { Config, AppConfig, Device, Styles, Theme, withTheme } from "@common";
import { AppIntro } from "@components";
import { connect } from "react-redux";

class Router extends React.PureComponent {
  constructor(props){
    super(props)
    this.state = {
      loading: true,
    };
  }

  componentWillMount() {
    NetInfo.getConnectionInfo().then((connectionInfo) => {
      this.props.updateConnectionStatus(connectionInfo.type != "none");
      this.setState({ loading: false });
    });
  }

  render() {
    return <AppIntro />;
  }
}

export default withTheme(
    connect(
    //   mapStateToProps,
    //   mapDispatchToProps
    )(Router)
);

更新：

根据 mychar 的建议成功解决错误： github.com/rt2zz/redux-persist/issues/1080 :

1. npm install --save @react-native-community/async-storage

2. 在 iOS 上，记得在 iOS 文件夹中执行“pod install”

3. 将存储更改为 AsyncStorage

   旧代码 => import storage from 'redux-persist/lib/storage'; new code => import AsyncStorage from '@react-native-community/async-storage';

   旧代码 => const persistConfig = { //... storage,

   新代码 => const persistConfig = { //... storage: AsyncStorage, >

但是，仍然收到此警告：
