webpack uglify 错误:意外的令牌:关键字(函数)

Question

我正在尝试运行npm运行构建，但我不能这样做。
我正在使用 webpack 2，但它让我在 uglifyJs
app.3e1e32973e47000acf37.js 中得到了一个ERROR来自 UglifyJs 意外令牌：关键字(函数([app.3e1e32973e47000acf37.js：130155,20] app.bundle 中的错误.js来自 UglifyJs

这是我的包.json

"devDependencies": {
"angular-animate": "^1.6.4",
"angular-aria": "^1.6.4",
"angular-sanitize": "^1.6.4",     
"babel-core": "^6.2.1",
"babel-loader": "^6.2.0",
"babel-preset-es2015": "^6.1.18",
"copy-webpack-plugin": "4.0.1",    
"html-webpack-plugin": "^2.7.1",    
"postcss-loader": "1.2.2",
"raw-loader": "^0.5.1",
"rimraf": "^2.5.1",
"style-loader": "^0.13.0",
"webpack": "2.2.0",
"webpack-dev-server": "2.2.0"
}
"scripts": {
"build": "rimraf dist && webpack -p --bail --progress --profile",
"server": "webpack-dev-server --port 8080 --history-api-fallback --inline --progress",
"start": "npm run server"
},

这是我的 webpack.config.js 文件

config.module = {
rules: [{
// JS LOADER
// Reference: https://github.com/babel/babel-loader
// Transpile .js files using babel-loader
// Compiles ES6 and ES7 into ES5 code
test: /.js$/,
loader: 'babel-loader',**strong text**
exclude: /node_modules/
}

这是我的巴别塔文件

{
"presets": ["es2015"]
}

当我将带有这个新测试对象的 webpack.config.js 文件从js更改为es6
时

config.module = {
rules: [{
// JS LOADER
// Reference: https://github.com/babel/babel-loader
// Transpile .js files using babel-loader
// Compiles ES6 and ES7 into ES5 code
test: /.es6$/,
loader: 'babel-loader',**strong text**
exclude: /node_modules/
}

我从 UglifyJs 收到 app.8c6dc5e29db45e3eb325.js 中的错误错误意外令牌：运算符 (>( [app.8c6dc5e29db45e3eb325.js：5564,32]

请让我知道我在这里运行npm 运行构建做错了什么？

你需要以这种方式更改你的 babel 配置

"devDependencies": {    
"babel-core": "^6.26.0",
"babel-loader": "^6.4.1",
"babel-plugin-transform-runtime": "^6.23.0",
"babel-polyfill": "^6.26.0",
"babel-preset-env": "^1.6.0",
"babel-preset-es2015": "^6.24.1",
"babel-preset-latest": "^6.22.0",
"babel-preset-stage-0": "^6.24.1"    
}

更新你的巴贝尔

{
"presets": [
"es2015",
"stage-0"
],
"plugins": [
["transform-runtime", {
"helpers": false,
"polyfill": false,
"regenerator": true,
"moduleName": "babel-runtime"
}]
]
}

并将此配置用于 webpack

config.module = {
rules: [{
// JS LOADER
// Reference: https://github.com/babel/babel-loader
// Transpile .js files using babel-loader
// Compiles ES6 and ES7 into ES5 code
test: /.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['env']
}
}
},

这应该可以解决问题。
