我正在尝试编写一个可以做一些事情的gulp任务

1. 安装Bower依赖项
2. 按顺序将这些依赖项转换为一个文件

我希望这样做而不必指定那些依赖项的路径.我知道有命令,bower list --paths但我不确定是否可以将它绑在一起.

有什么想法吗？

编辑

所以我试图使用gulp -bower文件,我收到一个eaccess错误,它没有生成连接文件.

gulpfile.js

var gulp = require('gulp');
var bower = require('bower');
var concat = require('gulp-concat');
var bower_files = require('gulp-bower-files');

gulp.task("libs", function(){
    bower_files()
    .pipe(concat('./libs.js'))
    .pipe(gulp.dest("/"));
});

bower.json

{
  "name": "ember-boilerplate",
  "version": "0.0.0",
  "dependencies": {
    "ember": "1.6.0-beta.1",
    "ember-data": "1.0.0-beta.7"
  }
}

我一直遇到这个错误

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: EACCES, open '/libs.js'

我试图让我的头围绕broccoli.js,但我遇到了一个错误.如果你查看我的GitHub仓库,你会看到我有一个看起来像这样的brocfile.js:

brocfile.js

var compileES6 = require('broccoli-es6-concatenator')
var pickFiles = require('broccoli-static-compiler');
var mergeTrees = require('broccoli-merge-trees')


var app = 'app'
app = pickFiles(app,{
    srcDir: '/',
    destDir: 'app-kit'
})

var appJS = compileES6(app, {
    inputFiles: ['/app-kit/**/*.js'],
    outputFile: '/dist/app.js'
})

module.exports = mergeTrees([appJS]);

我收到此错误:

我正在尝试编写一个泛型函数,只有在模型定义了关系但不特定于该模型时才会触发.

是否有模型的属性会告诉我该模型是否有任何关系,无论模型是什么或关系？
