问题描述

我收到此错误.昨天运行 gulp 运行良好，但今天早上(更改了 NO 代码)我收到了这个错误.

I'm getting this error. Running gulp yesterday worked perfectly fine, but this morning (changed NO code) and I'm getting this error.

我的 gulpfile.js 看起来像这样:

My gulpfile.js looks like this:

var gulp = require('gulp');

// Include Our Plugins
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var livereload = require('gulp-livereload');

var paths = {
    // using framework version of jquery
    scripts: [
        'public/assets/js/jquery.min.js',
        'public/assets/plugins/mustachejs/mustache.js',
        'public/assets/js/modernizr.js',
        'public/assets/js/bootstrap.min.js',
        'public/assets/js/placeholders.min.js',
        'public/assets/plugins/bootstrap-wysiwyg/bootstrap3-wysihtml5.all.min.js',
        'public/assets/plugins/bootstrap-wysiwyg/bootstrap3-wysihtml5.min.js',
        'public/assets/plugins/responsiveslides/responsiveslides.min.js',
        'public/assets/plugins/bxslider/jquery.bxslider.min.js',
        'public/assets/plugins/magnific-popup/magnific-popup.js',
        'public/assets/js/jquery.autocomplete.min.js',
        'public/assets/js/plugins/additems.js',
        'public/assets/js/plugins/farm/farm.js',
        'public/assets/js/plugins/plusminus.js',
        'public/assets/js/core.js'
    ]
};

// Concatenate & Minify JS
gulp.task('scripts', function() {
    return gulp.src(paths.scripts)
        .pipe(concat('all.js'))
        .pipe(gulp.dest('public/assets/js'))
        .pipe(rename('all.min.js'))
        .pipe(uglify())
        .on('error')
        .pipe(gulp.dest('public/assets/js'))
        .pipe(livereload());
});

// Watch Files For Changes
gulp.task('watch', function() {
    livereload.listen();
    gulp.watch(paths.scripts, ['scripts']);
});

// Default Task
gulp.task('default', ['scripts', 'watch']);

同样我没有改变任何东西，所以我不明白为什么今天早上它突然不想工作了.

Again I didn't change anything so I don't get why all of a sudden this morning it doesn't want to work.

推荐答案

以下帮助:

1. 安装 Gulp-util
2. 使用以下语句导入 Gulp-util:var gutil = require('gulp-util');
3. 最后，当你丑化代码时，像这样附加错误处理程序:.pipe(uglify().on('error', gutil.log))

我能够调试它.这是我包含的一个缩小文件中的语法错误.

I was able to debug it. It was a syntax error in one of the minified files I was including.
