Question

这是我的gulpfile中的一部分：

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javascripts/app.js：

中

我有一个例子：

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

我收到此错误：

GulpUglifyError: unable to minify JavaScript

这是我的package.json：

的一部分

    "animate.css": "^3.5.2",
    "aos": "^2.2.0",

    "streamqueue": "^1.1.1",
    "vinyl-buffer": "^1.0.0",
    "vinyl-source-stream": "^1.1.0"
  },

我还应该为ES6的gulp流程添加什么？

修改

所以关注es2017的babel bug：

我已安装：

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

改变了我的gulpfile：

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

我在编译过程中没有收到任何错误，但是当我在浏览器上运行代码时，我在浏览器控制台上收到此错误：

Uncaught ReferenceError: regeneratorRuntime is not defined

Answer 1

Had similar issue with gulp-uglify, and as I've found out it seems that minifying async/await is not supported with base gulp-uglify, so I switched to babel-minify, and it worked for me.

EDIT: For regeneratorRuntime is not defined error, I think that regenerator-runtime could be helpful.

Answer 2

我已经解决了替换问题：

.pipe(uglify()) 由 .pipe(minify())
