gulp 依赖在中间打破了 gulp

Question

有一天我的 gulp 脚本运行良好，现在是这样。

gulp.task('minify:dashboard', ['inject:dashboard'], function() {
  var assets;

  return gulp.src(paths.django.templates.root + '/__dashboard.html')
    .pipe($.replace('script src="{{ STATIC_URL }}dashboard', 'script src="compile'))

    .pipe($.useref({
      searchPath: '.'
    }))

    // versioning assets
    .pipe(indexHtmlFilter)
      .pipe($.rev())
      .pipe($.debug())
      .pipe(indexHtmlFilter.restore)

    // processing scripts
    .pipe(jsFilter)
      // .pipe($.uglify({
      //   preserveComments: $.uglifySaveLicense,
      //   compress: uglifyCompressOptions
      // }))
      .pipe($.size())
      .pipe(gulp.dest(paths.django.assets.dashboard + '/builds'))
      .pipe(jsFilter.restore)

    // updating references
    .pipe($.revReplace())
    // adding django static url reference
    .pipe($.replace('src="scripts', 'src="{{ STATIC_URL }}dashboard/builds/scripts'))
    .pipe(gulp.dest('compile/builds'));
});

这个任务本身就可以正常工作，例如

gulp minify:dashboard

但是，当我介绍一个新任务时

gulp.task('minify', ['minify:common', 'minify:dashboard']);

上面的任务gulp minify给了我这个

events.js:154
      throw er; // Unhandled 'error' event
      ^
Error: write after end
    at writeAfterEnd (/magneto/dashboard/node_modules/readable-stream/lib/_stream_writable.js:203:12)
    at StreamFilter.Writable.write (/magneto/dashboard/node_modules/readable-stream/lib/_stream_writable.js:239:20)
    at write (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:623:24)
    at flow (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:632:7)
    at DestroyableTransform.pipeOnReadable (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:664:5)
    at emitNone (events.js:80:13)
    at DestroyableTransform.emit (events.js:179:7)
    at emitReadable_ (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:448:10)
    at emitReadable (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:444:5)
    at readableAddChunk (/magneto/dashboard/node_modules/gulp-useref/node_modules/readable-stream/lib/_stream_readable.js:187:9)

奇怪的是，我删除了所有过滤器，即

```js

gulp.task('minify:dashboard', ['inject:dashboard'], function() {
  var assets;

  return gulp.src(paths.django.templates.root + '/__dashboard.html')
    .pipe($.replace('script src="{{ STATIC_URL }}dashboard', 'script src="compile'))

    .pipe($.useref({
      searchPath: '.'
    }))

    // versioning assets
    //.pipe(indexHtmlFilter)
      .pipe($.rev())
      .pipe($.debug())
      //.pipe(indexHtmlFilter.restore)

    // processing scripts
    //.pipe(jsFilter)
      // .pipe($.uglify({
      //   preserveComments: $.uglifySaveLicense,
      //   compress: uglifyCompressOptions
      // }))
      //.pipe($.size())
      //.pipe(gulp.dest(paths.django.assets.dashboard + '/builds'))
      //.pipe(jsFilter.restore)

    // updating references
    .pipe($.revReplace())
    // adding django static url reference
    .pipe($.replace('src="scripts', 'src="{{ STATIC_URL }}dashboard/builds/scripts'))
    .pipe(gulp.dest('compile/builds'));
});

```

然后任务gulp minify 工作得很好。是 gulp 或 gulp-filter 包有问题，还是我用错了？

我已经在 gulp-filter git repo 上发布了同样的问题，我认为这是 gulp 过滤器的一个错误。

这里应该做什么？

对于任何寻求答案的人，原来我更新到 gulp 4，从而打破了依赖关系。希望这会有所帮助。
