ERROR從UglifyJs意外標記PUNC«（»

Question

版本renderer.js：2.3.3的WebPack

您好

我試圖用Vuejs打造我的第一個電子的應用程序的一切，似乎是想偉大的，直到我來打包應用程序。

當我運行npm run dev一切工作就好了。

然而，當我運行npm build:darwin我收到以下錯誤

ERROR in renderer.js from UglifyJs Unexpected token punc «(», expected punc «:» [renderer.js:26813,14]

它確實最終編譯，但是當我運行應用程序時，我得到了死亡的白色屏幕。

從我讀，這可能是因爲Uglifyjs不編譯器ES6，但你可以通過在.babelrc文件

"renderer": { 
    "presets": [ 
    ["es2015", { "modules": false }], 
    "stage-0" 
    ] 
} 

以下我不知道如何調試這克服。任何幫助將不勝感激。

感謝

你可以嘗試安裝this版本的uglify，它呼籲uglify-es，它是：

JavaScript分析器，壓榨機/壓縮機和美化工具包ES6 +

uglify-es npm link

在我的情況下，我已經安裝babel插件來處理這個問題。 如果您想嘗試，你應該這樣做：

添加到您的package.json

"babel-core": "latest", 
"babel-loader": "latest", 
"babel-plugin-transform-async-to-generator": "latest", 
"babel-plugin-transform-runtime": "latest", 
"babel-preset-es2015": "latest", 
"babel-runtime": "latest" 

設置你webpack.config文件是像（這是我的爲例）：

const path = require('path') 
const webpack = require('webpack') 

module.exports = { 
    entry: './src/main.js', 
    output: { 
     path: path.resolve(__dirname, './dist'), 
     publicPath: '/dist/', 
     filename: 'build.js' 
    }, 
    module: { 
     rules: [ 
      { 
       test: /\.vue$/, 
       loader: 'vue-loader' 
      }, 
      { 
       test: /\.js$/, 
       loader: 'babel-loader', 
       exclude: /node_modules/ 
      }, 
      { 
       test: /\.(png|jpg|gif|svg)$/, 
       loader: 'file-loader', 
       query: { 
        name: '[name].[ext]?[hash]' 
       } 
      }, 
      { 
       test: /\.scss$/, 
       use: ['style-loader', 'css-loader', 'sass-loader'] 
      } 
     ] 
    } 
} 

if (process.env.NODE_ENV === 'production') { 
    module.exports.devtool = '#source-map' 
    module.exports.plugins = (module.exports.plugins || []).concat([ 
     new webpack.optimize.UglifyJsPlugin({ sourceMap: true, compress: { warnings: false }}) 
    ]) 
} 

套裝您的.babelrc文件應如下所示：

{ 
    "presets": ["es2015"], 
    "plugins": ["transform-runtime", "transform-async-to-generator"] 
} 

希望它有幫助:)
