javascript - 'createPolyglotMiddleware' 未定义

Question

我正在尝试按照此处的说明设置 redux-polyglot：https ://www.npmjs.com/package/redux-polyglot

我的问题是，当我添加该const polyglotMiddleware = createPolyglotMiddleware(部分时，我收到一条错误消息，告诉我它没有定义。我无法弄清楚我哪里出错了。任何人都可以帮忙吗？

这是我的减速器代码：

import { createStore, combineReducers, applyMiddleware } from 'redux';
import { polyglotReducer } from 'redux-polyglot';

const rootReducer = combineReducers({
    polyglot: polyglotReducer
});


const polyglotMiddleware = createPolyglotMiddleware(
    'ACTION_TO_CATCH',
    action => action.payload.locale,
    locale => new Promise(resolve => {
        // perform async here
        resolve({
            hello: 'bonjour',
        });
    }),
)

const store = createStore(rootReducer, {}, applyMiddleware(polyglotMiddleware));

export default store;

我认为您忘记了 import createPolyglotMiddleware，请在模块顶部尝试以下操作：

import { polyglotReducer, createPolyglotMiddleware } from 'redux-polyglot';
