本文介绍了JavaScript在angular js gulp sourcemap ngannonate中用babel堆内存不足的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着跟版网的小编来一起学习吧！

问题描述

我在我的 Angular JS 项目中使用 es6 语法，但是在运行 gulp build 时会抛出错误，在 github 上搜索，所以但有人说这是由于 gulp uglify 而导致的错误，而有人说这是 babel问题和其他说 ng-annonate 问题.

I am using es6 syntax in my angular JS project but it throws error when run gulp build, search over github and So but some saying this is error due to gulp uglify while some say this is babel issue and other say ng-annonate issue.

gulp/.babelrc

{
    "presets": ["es2015"],
    "plugins": ["syntax-decorators", "ng-annotate"] // this line is added after seeking for solution
}

gulp/build.js相关代码

.pipe(jsFilter)
    .pipe($.sourcemaps.init())
    .pipe($.babel({"presets": [ ["es2015", { "modules": false} ] ], compact: false}))
    .pipe($.ngAnnotate())
    .pipe($.uglify({
      preserveComments: $.uglifySaveLicense
    })).on('error', conf.errorHandler('Uglify'))
    .pipe($.sourcemaps.write('.'))
    .pipe(jsFilter.restore)

还尝试了 .pipe(uglify({compress: {sequences: false, join_vars: false}})) 根据 这个解决方案.但无济于事

also tried .pipe(uglify({compress: {sequences: false, join_vars: false}})) as per this solution . but does not help

这里是执行gulp build

推荐答案

主要原因是 uglify 插件无法使用 es6 语法，所以这样做

The main cause was uglify plugin which does not work with es6 syntax so did this

  1. npm install babel-cli -g

  2. bower install gulp-uglify-es --save-dev

在gulp/build.js

var uglify = require('gulp-uglify-es').default;

然后在下面写到 gulp 任务

and wrire belowcinside gulp task

 .pipe($.sourcemaps.init())
    .pipe($.babel({"presets": [ ["es2015", { "modules": false} ] ], compact: false}))
    .pipe($.ngAnnotate())
    .pipe(uglify()).on('error', conf.errorHandler('Uglify'))
    .pipe($.sourcemaps.write('.'))
