Question

我已经被问了好几个小时了。每当我尝试运行WebPack时，它会给我模块构建错误，它会抱怨＆lt;。我在这个网站和其他网站上尝试了很多解决方案，但我仍然无法弄明白。任何帮助将不胜感激。

main.js

import Main from './main.jsx';

main.jsx

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route, Link } from 'react-router-dom';
import { Switch } from 'react-router';

class Nav extends React.Component {
  render() {
    return {
      <div>hello</div>
    }
  }
}

class App extends React.Compnent {
  render() {
    return {
      <div>
        <Nav />
      </div>
    }
  }
}

ReactDOM.render (
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById("mainContent")
);

webpack.config.js

const path = require('path');

module.exports = {
    entry: './js/main.js',
    output: {
        path: path.resolve(__dirname, 'docs'),
        filename: 'file.js'
    },
    devServer: {
      contentBase: path.join(__dirname, "docs"),
      port: 9000
    },
    module: {
      loaders: [
            { test: /\.jsx$/, loader: 'babel-loader', exclude: /node_modules/ },
        ]
    },
};

也尝试了

    module: {
      loaders: [
            { test: /\.jsx$/, loader: 'babel-loader', exclude: /node_modules/ , query: {presets:['es2015', 'react']} },
        ]

简单地说是（）而不是{}。感谢Sterling Archer指出这一点。
