所以我正在尝试关注React的this教程(后来我将通过认证和PostgreSQL集成)。我已经注意到他的反应路由器已经过时,因此使用了最高评论来解决这个问题。但是,在react-router-loader
文件中安装webpack.config.js
后,我收到以下错误:
ERROR in ./client/index.js
Module parse failed: /Users/shirazchokshi/react-redux/client/index.js
Unexpected token (7:2)
You may need an appropriate loader to handle this file type.

| render((
| <Router>
| <div>
| <Route path="/" component={App} />
@ ./client/index.js 11:29-90
@ multi webpack-hot-middleware/client ./client/index.js
这没有意义,因为我相信我已经在配置文件中加载了所有正确的加载器。尽管如此,下面是上下文的一些其他文件:
/client/index.js
import React from 'react';
import {render} from 'react-dom';
import { BrowserRouter as Router, Route, browserHistory } from 'react-router-dom';
import App from './component/App';
render((
<Router>
<div>
<Route path="/" component={App} />
</div>
</Router>
), document.getElementById('app'));
/client/component/App.js
import React from 'react';
import NavigationBar from './NavigationBar';
class App extends React.Component{
render() {
return(
<div className="container">
Hello World!
</div>
);
}
}
export default App;
webpack.config.dev.js
import path from 'path';
import webpack from 'webpack';
export default {

答案 0 :(得分:3)
从package.json
,我发现您正在使用webpack v3.4.1
。为此,您需要使用module.rules
代替module.loaders
module: {
rules: [
{
test: /\.js$/,
include: path.join(__dirname, '/client'),
use: ['react-hot-loader', 'babel-loader']
}
]
},
请参阅 documentation 和 migration guide

在你的/client/index.js中,“render”方法来自哪里?你有没有从ReactDOM导入它?另外,我认为你可能还有一个额外的括号:
render((
