gulp-uglify 流错误后 gulp-重命名

Question

这里的gulp菜鸟，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"))
}

这个想法是产生普通的（非缩小的）JS和一个缩小的版本。

但是，Uglify 抛出了一个错误：

fy-js\tools\node.js:22:1), <anonymous>:2353:20)',
  showStack: false,

似乎它不喜欢它正在管道传输的 JS 的某些内容，但如果在第一次 gulp.dest（） 调用之前调用它，Uglify 不会抛出错误（我确实得到了缩小的代码）。

这篇文章表明源映射可能是一个问题，并使用gulp-ignore 来排除它们。试过了，没有用;同样的错误。

我在这里错过了一些明显的东西吗？

所以是源地图导致Uglify犹豫不决。将 Browserify 与其他插件相结合似乎存在一个更普遍的问题，这与 Browserify 想要在缓冲区中的内容和其他插件想要在流中的东西有关。

为此，我重新找到了我的任务功能：

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);
}

没有我想要的那么优雅，但它完成了工作，我需要继续这个项目（而不是在构建过程中陷入困境）。
