以上代碼，用webpack打包后可以正常編譯，并在瀏覽器運(yùn)行顯示app組件內(nèi)容。
但是只有導(dǎo)入import {createStore} from "redux"或者// import {Provider} from "react-redux";
//去掉redux的導(dǎo)入就正常，導(dǎo)入redux就出問題，因?yàn)闊o(wú)redux可以正常編譯，可以排除一些可能

 import React from "react";
    import ReactDOM from "react-dom";
    // import {createStore} from "redux";
    import {Provider} from "react-redux";
    
    import App from "./App.js";
    import reducer from "./reducers/index.js"
    // let store  = createStore(reducer);
    
    ReactDOM.render(
    // <Provider store={store}>
    //     <App></App>
    // </Provider>
    <App></App>
    ,
    document.getElementById("app-container")
)
