Internet Explorer 10及更低版本的React,WebPack和Babel生成SCRIPT1002:语法错误

标签: reactjs internet-explorer webpack webpack-dev-server babel

我已经阅读了有关类似问题的多个主题并尝试了一些命题,但没有结果。

我遵循了与 React.js WebPack 3 相关的一些教程。因此,除了 IE 10 以及更低版本之外,应用程序在所有浏览器(此时)都运行良好。错误指向bundle.js(一旦我使用配置Nr.1):
SCRIPT1002: Syntax error和行 - const url = __webpack_require__(83);

使用配置Nr2。,在本地服务器上:SCRIPT1002: Syntax error - 与eval()对齐 并且相同的配置,但在远程服务器上运行会产生一些不同的错误:

SCRIPT5009: 'Set' is undefine

WebPack配置Nr1。:

const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
  template: './index.html',
  filename: 'index.html',
  inject: 'body'
})
module.exports = {
  entry: './index.js',
  output: {
    filename: 'bundle.js'
  },
  module: {
    loaders: [
      {
        test: /\.json$/,
        exclude: /node_modules/,
        loader: 'json-loader'
      },
      {
        test: /\.css$/,
        loader: "style-loader!css-loader"
      }
    ],
    rules: [
      {
        test: /\.js$/,
        exclude: /(node_modules)/,      
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['env', 'react']
          }
        }
      }
    ]
 },
   devServer: {   
      historyApiFallback: true,
      contentBase: './'
  },
 plugins: [HtmlWebpackPluginConfig]
}

WebPack配置Nr2。:

                    plugins: ["transform-es2015-arrow-functions"]
                  }
                },
                include: sourcePath
            },
            {                
                test: /\.css$/,
                exclude: /node_modules/,
                use: ExtractTextPlugin.extract({
                    fallback: 'style-loader',
                    use: [
                        { loader: 'css-loader', options: { minimize: true } },
                        'postcss-loader',
                        'sass-loader'
                    ]
                })
            },
            {
                test: /\.(eot?.+|svg?.+|ttf?.+|otf?.+|woff?.+|woff2?.+)$/,
                use: 'file-loader?name=assets/[name]-[hash].[ext]'
            },
            {
                test: /\.(png|gif|jpg|svg)$/,
                use: [
                    'url-loader?limit=20480&name=assets/[name]-[hash].[ext]'
                ],
                include: staticSourcePath
            }
        ]
    }
}; 

此外,我已将 es2015 添加到预设:['env', 'react', 'es2015']plugins: ["transform-es2015-arrow-functions"],但没有任何意义。

如果babel加载器不能完全配置错误或其他什么,我认为整个应用程序将无法启动。我相信应该用预设或他们的订单来完成......需要经验丰富的开发人员的建议

更新 我已将devtool更改为inline-cheap-module-source-map并将错误指向overlay.js - > const ansiHTML = require('ansi-html');

2 个答案:

答案 0 :(得分:3)

package.json 文件中

webpack-dev-server 的版本更改为版本“2.7.1”(或更早版本)。

"webpack-dev-server": "2.7.1"

然后执行 npm install etvoilà。

这解决了我的问题。

2.7.1之后的所有版本都给出了与您类似的错误。

答案 1 :(得分:1)

只需将devtools : "source-map"添加到您的Webpack配置中,如下所示:

const path = require('path');
module.exports = {
  devtool: "source-map",
  entry: ['babel-polyfill', path.resolve(__dirname, './js/main.js')],
  mode: 'production',
  output: {
    path: __dirname+'/js/',
    filename: 'main-webpack.js'
  }
};

这将删除eval并将您的源地图更改为IE支持。

  

更新我已将devtool更改为inline-cheap-module-source-map并将错误指向overlay.js - > const ansiHTML = require('ansi-html');

要支持ES6语法,您必须使用Babel编译JavaScript代码。
