我的webpack.config.js

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

module.export = {
  entry: './src/index.js',
  output: {
    path: path.join(__dirname, '/build'),
    filename: 'index_bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      }
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/templates/index.html'
    })
  ]
};

我的巴贝尔rc

{
  "presets": ["env", "react"]
}

./src/index.js 5:16模块解析失败中的错误：意外标记（5:16）您可能需要一个适当的加载程序来处理此文件类型。从“./components/App”导入App；reactdom.render(，document.getElementById('root'))；//ReactDom.Render（“Hello User”,Document.GetElementById（“root”））；@multi(webpack)-dev-server/client？http://localhost:8080(webpack)/hot/dev-server.js./src main2

如果需要，我可以通过git repo共享代码库。非常感谢任何帮助。

问题是webpack配置文件中的错误。

您有module.export，这不正确。应该是模数出口

工作实例

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

module.exports = {
  entry: './src/index.js',
  output: {
    path: path.join(__dirname, '/build'),
    filename: 'index_bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      }
    ]
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './src/templates/index.html'
    })
  ]
};
