reactjs - 通过 webpack 编译时出现此错误 Unexpected token, expected ","

Question

在编译此代码时，我收到此错误SyntaxError: Unexpected token, expected ","。我希望你能帮我解决这个问题。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

Answer 1

你的电话createStore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)));

正确的函数签名是：

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