Reactjs Compose Enhanser不是一个函数

当我运行react应用程序时，它会显示以下错误：

未捕获类型错误：composeEnhancers不是函数

这是我的商店代码

import { applyMiddleware, createStore, compose } from "redux";

import thunk from "redux-thunk";
import logger from "redux-logger";
import rootReduer from "./root-Reducer";
import { persistStore } from "redux-persist";

let middlewares;
let composeEnhancers;
if (process.env.NODE_ENV !== "production") {
  const composeEnhancers =
  window['__REDUX_DEVTOOLS_EXTENSION_COMPOSE__'] || compose;
  middlewares = [thunk, logger];
} else {
  middlewares = [thunk];
  composeEnhancers = compose;
}

// hide action with state in console.log in deplyment app.
export const store = createStore(
  rootReduer,
  composeEnhancers(applyMiddleware(...middlewares))
);

export const persistor = persistStore(store);

如何解决此错误？

您已在第一个

if

块中重新声明了

composeEnhancers

。删除

组件增强器之前重新声明的
常量
。可能看起来像

if (process.env.NODE_ENV !== "production") {
  composeEnhancers = window['__REDUX_DEVTOOLS_EXTENSION_COMPOSE__'] || compose;
  middlewares = [thunk, logger];
  //... other codes
