gulp-uglify stream在gulp-rename後出錯

Question

gulp noob在這裏，我看到奇怪的行爲與gulp-uglify。

這是我的任務：

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")) 
} 

的想法是產生正常（非精縮）和JS的縮小版本。

然而，醜化拋出一個錯誤：

[16:20:26] Using gulpfile C:\play\untitled\gulpfile.js 
[16:20:26] Starting 'browserify'... 
[16:20:28] { [Error: C:\play\untitled\public\js\main.min.js: Unexpected  token: punc (:)]

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

這似乎不喜歡的東西，關於它的管道輸送，但醜化不會引發錯誤，如果它是第一個gulp.dest之前稱爲JS（ ）電話（我確實得到縮小的代碼）。

This post表示源地圖可能是一個問題，並使用gulp-ignore來排除它們。試過了，它不起作用;同樣的錯誤。

我在這裏遺漏了一些明顯的東西嗎？

感謝， 傑夫

所以這是造成醜化在所不惜源地圖。似乎有一個更普遍的問題，將Browserify與其他插件相關聯，這些插件與Browserify相關，希望緩衝區中的內容和其他插件需要流中的內容。

爲此，我refind我的任務功能，這一點：

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); 
} 

不優雅，我想它，但它能夠完成任務，我需要這個項目破解的（和不會在構建過程中陷入困境）。
