丑化失败.意外字符'`' [英] Uglification failed. Unexpected character '`'

问题描述

gulp-uglify 无法丑化这段代码:

gulp-uglify is unable to uglify this piece of code:

    var alertString = `<?xml version="1.0" encoding="UTF-8" ?>
        <document>
          <alertTemplate>
            <title>${title}</title>
            <description>${description}</description>
          </alertTemplate>
        </document>`

它抱怨字符:`.该字符适用于苹果的 JS 框架.我看不到 uglify 包中的任何内容来忽略这些字符和其中的文本字符串.我是否遗漏了文档中的某些内容?

it complains at the character: `. The character is valid for the apple's JS framework. I can't see anything inside the uglify package to ignore those characters and the text string inside it. Am i missing something from the documentation?

推荐答案

Gulp-uglify 还没有对 ECMAScript 2015(又名 ES6，又名 Harmony)的官方支持，但稍作修改即可使用开发中的存储库.

Gulp-uglify has yet no official support for ECMAScript 2015 (aka ES6, aka Harmony) but with a little modification the on-development repository can be used.

操作方法:

1. 打开控制台进入

cd node_modules/gulp-uglify

1. 编辑 package.json

依赖项": {uglify-js":git+https://github.com/mishoo/UglifyJS2.git#harmony"},

1. 控制台输入:

npm 更新

它已准备好再次运行 .pipe(uglify())

替代解决方案

1. 通过 npm 下载以下内容:

1. Download the following via npm:

npm install --save-dev gulp-uglify gulp-babel babel-preset-es2015

1. 在 gulpfile.js 中添加以下要求:

1. Add the following requires in the gulpfile.js:

var babel = require('gulp-babel'),uglify = require('gulp-uglify');

1. gulp 任务如下:

gulp.task('uglify', function(){gulp.src('*.js').pipe(通天塔({预设:['es2015']})).pipe(uglify().on('error', function(e){控制台.log(e);})).pipe(gulp.dest('js'));});

它的作用是将所有 EcmaScript 2015 JS 代码转换为 EcmaScript5，然后对其进行 uglifying.

What this does is transpile all the EcmaScript 2015 JS code to EcmaScript5 and then uglifies it.
