Question

Gulp noob在这里，我看到了gulp-uglify的奇怪行为。

这是我的任务：

var gulp = require ("gulp");
var util = require ("gulp-util");
var clean = require ("gulp-clean");
var cleanCSS = require ("gulp-clean-css");
var debug = require ("gulp-debug");
var filesize = require ("gulp-filesize");
var rename = require ("gulp-rename");
var sass = require ("gulp-ruby-sass");
var browserify = require (BROWSERIFY);
var source = require ("vinyl-source-stream");
var buffer = require ("vinyl-buffer");
var sourceMaps = require("gulp-sourcemaps");
var babelify = require ("babelify");
var uglify = require ("gulp-uglify");
var concatFileNames = require ("gulp-concat-filenames");
var header = require ("gulp-header");

function browserifyTask () {

    return browserify ("./app/main.js")
        .transform(babelify)
        .bundle()
        .pipe (source("main.js"))
        .pipe (buffer())
        .pipe (sourceMaps.init({loadMaps: true}))

        .pipe (sourceMaps.write("./")) // Ensure the source map gets written
        .pipe (gulp.dest("./public/js"))

        // Now do production build stuff

        .pipe (rename("main.min.js"))
        .pipe (sourceMaps.init({loadMaps: true}))
        .pipe (uglify().on ("error", util.log))
        .pipe (sourceMaps.write("./")) // Ensure the source map gets written
        .pipe (gulp.dest("./public/js"))
}

这个想法是生成普通（非缩小）JS和缩小版本。

但是，Uglify会抛出错误：

fy-js\\tools\\node.js:22:1), <anonymous>:2353:20)',
  showStack: false,
  showProperties: true,
  plugin: 'gulp-uglify' }

看起来它似乎不喜欢关于JS的东西，但是如果在第一次gulp.dest（）调用之前调用了它，那么Uglify不会抛出错误（我确实得到了缩小的代码）。

This post表示源地图可能是一个问题，并使用gulp-ignore来排除它们。尝试过，它没有用;同样的错误。

我错过了一些明显的东西吗？

谢谢，杰夫

因此，源地图导致Uglify无视。似乎有一个更普遍的问题，将Browserify与其他插件相结合，这些插件与Browserify有关，希望缓冲区和其他插件需要流中的东西。

为此，我将任务功能改为：

function browserifyTask () {

    function doBrowserify (isProduction) {
        browserify ("./app/main.js")
            .transform(babelify)
            .bundle()
            .pipe (source("main.js"))
            .pipe (isProduction ? rename("main.min.js") : util.noop())
            .pipe (buffer())
            .pipe (sourceMaps.init({loadMaps: true}))
            .pipe (isProduction ? uglify().on ("error", util.log) : util.noop())
            .pipe (sourceMaps.write("./")) 
            .pipe (gulp.dest("./public/js"))
    }

    doBrowserify(false);
    doBrowserify(true);
}

不像我喜欢它那样优雅，但是它完成了工作，我需要继续使用这个项目（而不是在构建过程中陷入困境）。
