gulp依赖任务 - browserify和pre-browserify任务

Question

我有以下gulpfile

我正在使用emberate,它会在生成的文件(client/.index.js在本例中)被写入时调用回调.现在browserify任务取决于该文件,所以它不应该在嵌入完成之后运行.但是我得到了不同的结果,有时它会起作用,有时我会得到这个:

错误:无法从'/ Users/myuser/workspace/myproject'中找到模块'./client/.index.js'

来自browserify(是的,文件还没有)..我不确定我做错了什么,我done在我的emberate任务中作为回调,而浏览器任务取决于emberate ..我错过了什么？

编辑:发现一个小模式,如果我运行它并没有错误,下次我运行时gulp我得到错误,但下次我没有,所以它是每隔一次oO

如果我跑gulp emberate,那很有效.然后,如果我运行gulp browserify它运行以下:

[gulp] Using file /Users/myuser/workspace/myproject/gulpfile.js
[gulp] Working directory changed to /Users/myuser/workspace/myproject
[gulp] Running 'clean'...
[gulp] Finished 'clean' in 3.11 ms
[gulp] Running 'emberate'...
[gulp] Finished 'emberate' in 22 ms
[gulp] Running 'browserify'...
[gulp] Live reload server listening on: 35729

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: Cannot find module './client/.index.js' from '/Users/myuser/workspace/myproject'
    at /Users/myuser/workspace/myproject/node_modules/browserify/node_modules/resolve/lib/async.js:36:25
    at load (/Users/myuser/workspace/myproject/node_modules/browserify/node_modules/resolve/lib/async.js:54:43)

    at /Users/myuser/workspace/myproject/node_modules/browserify/node_modules/resolve/lib/async.js:16:47
    at Object.oncomplete (fs.js:107:15)

这个最新版本似乎可以工作,但是在监视期间如果文件被更改,它不会清理client/.index.js文件,而是继续添加它oO(尽管运行gulp emberate有或没有clean依赖工作正常......).

看起来 中存在一个错误emberate，涉及使用一个进程时的模板，该进程gulp.watch正在执行。

这是我的最终结果gulpfile.js：

  var path = require('path');
  var gulp = require('gulp');
  var less = require('gulp-less');
  var refresh = require('gulp-livereload');
  var clean = require('gulp-clean');
  var source = require('vinyl-source-stream');
  var emberate = require('emberate');
  var browserify = require('browserify');

  gulp.task('less', function () {
    return gulp.src('./client/styles/*.less')
      .pipe(less({
        paths: [
          path.join(__dirname, 'client', 'styles')
        ]
      }))
      .pipe(gulp.dest('./dist/styles'))
      .pipe(refresh());
  });

  gulp.task('clean', function () {
    return gulp.src('./client/.index.js', { read: false })
      .pipe(clean());
  });

  gulp.task('emberate', ['clean'], function () {
    return emberate('./client', { pods: true })
      .pipe(source('.index.js'))
      .pipe(gulp.dest('./client'));
  });

  gulp.task('browserify', ['emberate'], function () {
    return browserify('./client/.index.js')
      .bundle()
      //Pass desired output filename to vinyl-source-stream
      .pipe(source('application.js'))
      // Start piping stream to tasks!
      .pipe(gulp.dest('./dist/scripts/'))
      .pipe(refresh());
  });

  gulp.task('watch', function () {
    gulp.watch('./client/styles/*.less', ['less']);
    gulp.watch('./client/**/*.{js,hbs}', ['browserify']);
  });

 gulp.task('default', ['less', 'browserify', 'watch']);

效果很好:)
