我正在关注 react 导航文档,react-navigation-redux-helpers 的文档,但总是向我抛出这个错误。此外,如果我删除了persistGate,错误会得到修复,但我需要保留一些数据,所以这不应该是一个选项这是我的 store.jsimport { createStore, applyMiddleware } from 'redux';import { persistStore, persistReducer } from 'redux-persist';import { AsyncStorage } from 'react-native';import { createReactNavigationReduxMiddleware } from 'react-navigation-redux-helpers';import Reducer from './reducers/index';const persistConfig = { key: 'root', storage: AsyncStorage, blackList: [],};const AppReducer = persistReducer(persistConfig, Reducer);const middleware = createReactNavigationReduxMiddleware( (state) => state.navigation,);export const store = createStore(AppReducer, applyMiddleware(middleware));export const persistor = persistStore(store);这是我的 app-with-state.jsimport AppNavigator from './AppNavigator';const AppNavigatorWithState = createReduxContainer(AppNavigator);class ReduxNavigation extends React.Component { render() { const { state, dispatch } = this.props; return <AppNavigatorWithState navigation={state} dispatch={dispatch} />; }}const mapStateToProps = (state) => ({ state: state.navigation,});export default connect(mapStateToProps)(ReduxNavigation);这是我的 AppNavigator.jsconst Main = createStackNavigator( { Home: Home, Movie: Movie, Category: Category, }, { defaultNavigationOptions: { header: Header, }, },);const TabNavigator = createBottomTabNavigator({ Home: { screen: Main, navigationOptions: { tabBarIcon: <Icon icon='🏠' />, }, }, About: { screen: About }, Lucky: { screen: Lucky }, Profile: { screen: Profile }, }, { tabBarOptions: { activeTintColor: 'white', activeBackgroundColor: '#65a721', }, },);//const App = createAppContainer(TabNavigator);export default TabNavigator;

我知道为时已晚,但它应该可以帮助其他人:))
在你的 mystore.js 中
const middleware = createReactNavigationReduxMiddleware(
(state) => state.navigation,
)
应该是这样的:
const middleware = createReactNavigationReduxMiddleware(
(state) => state.router,
)

我也遇到了这个错误,我没有找到任何线索,然后卡住了。经过几个小时的调试,这是因为我犯了愚蠢的错误。
这是我的错误案例:
const customContent = ({props}) => { }
实际上,props
不需要{}
。只需调用(props)
like 即可修复错误。
这是正确的案例:
const customContent = (props) => { }
{}
打电话时请不要加props
。
希望它对像我这样出错的人有所帮助。
