Question

我坚持同样的错误，我需要新的眼睛寻求帮助......我对“适当的装载机”感到困惑。我以为这是来自webpack文件中的一个不正确的正则表达式。我查看了babel文档和issue以获得指导。

这是错误......

./src/index.js中的错误模块解析失败：意外的令牌（6:16）

您可能需要适当的加载程序来处理此文件类型。

@ multi（webpack）-dev-server / client？http://localhost:8080 ./src

这是我的 src / index.js

import React from 'react'
import ReactDOM from 'react-dom'

import App from './Components/App'
ReactDOM.render(<App />, document.getElementById('root'))

.babelrc

{
  "presets": ["env", "react"],
  "env": {
    "development": {
      "plugins": [["react-transform",{
      "transforms": [{
        "transform": "react-transform-hmr",
        "imports": ["react"],
        "locals": ["module"]
      }]
    }]]
    }
  }
}

webpack.dev.config.js

const path = require('path')
const webpack = require('webpack')
const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'build'),
    publicPath: '/',
  },
  module: {
    rules: [
      { test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/,
        include: [path.resolve(__dirname, "src")]
      }
    ],
  },
  devServer: {
    historyApiFallback: true,
    inline: true,
    hot: true,
  },
  plugins: [
    new HtmlWebpackPlugin({template: 'src/index.html'}),
    new webpack.HotModuleReplacementPlugin()
    ],
}

和我的 package.json
