Question

在编译此代码时，出现此错误 SyntaxError：意外的令牌，预期为“，” 。我希望你能帮我这个忙。在线错误（13:39）

import { createStore, applyMiddleware } from 'redux';
import { composeWithDevTools } from 'redux-devtools-extension';
import thunk from 'redux-thunk';
import rootReducers from './reducers';

const initialState = {};

const middleware = [thunk];

const store = createStore({
    rootReducers,
    initialState,
    composeWithDevTools(applyMiddleware(...middleware))
});

export default store;

谢谢

您对createStore的呼叫是错误的。它应该是参数列表，而不是对象：

const store = createStore(rootReducers, initialState, composeWithDevTools(applyMiddleware(...middleware)));

正确的功能签名是：

 createStore(reducer, [preloadedState], [enhancer])
