Question

我正在努力让https://domainname.com与es2015合作。

在指示我.babelrc 之前，请注意我已经添加两个es2015并作出反应（确定，但这里没有反应）。

它具有

功能

import { default as Logary, Targets, getLogger, build } from 'logary';

这是.babelrc：

{
  "presets": ['es2015', 'react']
}

和webpack.config.js

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

module.exports = {
  devtool: 'source-map',
  entry: [
    'webpack-hot-middleware/client?reload=true',
    './index.js'
  ],
  output: {
    path: path.resolve('./dist'),
    filename: '[name].js',
    publicPath: '/'
  },
  loaders: [
    { test: /\.js$/,
      loader: 'babel-loader',
      exclude: /node_modules/
    },
    { test: /\.css$/, loader: "style!css" },
    { test: /\.(png|jpg|jpeg|gif|woff)$/, loader: 'url?limit=8192' },
    { test: /\.(otf|eot|ttf)$/, loader: "file?prefix=font/" },
    { test: /\.svg$/, loader: "file" }
  ],
  plugins: [
    new HtmlWebpackPlugin({
      filename: 'index.html',
      template: 'index.template.html'
    }),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('development')
    })
  ],
  resolve: {
    extensions: ['', '.js']
  }
}

给出错误：

ERROR in ./index.js
Module parse failed: /Users/h/logary-js/examples/webpack/index.js Line 1: Unexpected token
You may need an appropriate loader to handle this file type.
| import { default as Logary, Targets, getLogger, build } from 'logary';
|
| // once per site/app

为什么不处理import-token？

您的webpack.config.js结构不正确。 Webpack并不能识别所有的加载器。具体来说，您需要将loaders属性放在模块部分中，如下所示：

module: {
   loaders: [
    { test: /\.js$/,
      loader: 'babel-loader',
      exclude: /node_modules/
    },
    { test: /\.css$/, loader: "style!css" },
    { test: /\.(png|jpg|jpeg|gif|woff)$/, loader: 'url?limit=8192' },
    { test: /\.(otf|eot|ttf)$/, loader: "file?prefix=font/" },
    { test: /\.svg$/, loader: "file" }
  ],
}

webpack + babel - 反应，意外令牌'导入'
