异步等待+ Gulp - GulpUglifyError:无法缩小JavaScript？

Question

这是我的文件里的一部分：

gulp.task('compile-js', function () {
    // app.js is your main JS file with all your module inclusions
  return browserify({
    extensions: ['.js', '.jsx'],
    entries: 'javascripts/app.js',
    debug: true
  })
  .transform('babelify', { presets: ['es2015', 'react'] })
  .bundle()
  .pipe(source('bundle.min.js'))
  .pipe(buffer())
  .pipe(sourcemaps.init())
  .pipe(uglify())
  .pipe(sourcemaps.write('./maps'))
  .pipe(gulp.dest('dist'))
  .pipe(livereload())
})

在我的javascripts/app.js里

举个例子，我有：

async function write () {
    var txt = await read();
    console.log(txt);
  }

我知道这个错误：

GulpUglifyError: unable to minify JavaScript

这是我的package.json的一部分：

  },

对于ES6，我还应该添加到我的吞咽过程中吗？

编辑：

因此，按照babel 文档 for es2017：

我安装了：

npm install --save-dev babel-preset-es2017

改变了我的吞咽文件：

...
.transform('babelify', {
    presets: ['es2015', 'es2017', 'react'],

编译过程中没有任何错误，但在浏览器上运行代码时，浏览器控制台上会出现此错误：

Uncaught ReferenceError: regeneratorRuntime is not defined

Answer 1

gulp uglify也有类似的问题，正如我所发现的，基gulp-uglify似乎不支持缩小异步/等待，所以我切换到了巴别化，它对我起了作用。

编辑:对于regeneratorRuntime is not defined错误，我认为再生器-运行时可能会有所帮助。

Answer 2

我已经解决了这个问题

.pipe(uglify()) by .pipe(minify())
