React Native Error:您当前使用的是NODE_ENV==='production'使用Redux的小型代码

这里是我的代码:

webpack.config.js

 var path = require('path');

module.exports = {
  mode: 'production',
  entry: "./App.js",
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
};

应用程序js

import * as React from "react";
import { Provider } from "react-redux";
import { createStore  } from "redux";
import { reducers } from "./reducers";

import { Drawer } from "./Navigation";
import LibraryReducer from "./reducers/LibraryReducer";

export default class App extends React.Component {
  render() {
    const store = createStore(LibraryReducer)
    return (
      <Provider store={store}>
        <Drawer />
      </Provider>

    );
  }
}
