我正在尝试让 broccolijs 使用 broccoli-less 编译更少文件的目录。我已将“预处理”功能更改如下：

var compileLess = require('broccoli-less')
var pickFiles = require('broccoli-static-compiler')

function preprocess (tree) {
  tree = filterTemplates(tree, {
    extensions: ['hbs', 'handlebars'],
    compileFunction: 'Ember.Handlebars.compile'
  })
  tree = filterCoffeeScript(tree, {
    bare: true
  })
  tree = compileLess(tree, {
      compress: false,
  })
  return tree
}

在我的项目文件夹中，我有一个名为“less”的目录，我将其包含在 Brocfile.js 中：

var lessStyles = 'less'
lessStyles = pickFiles(lessStyles, {
  srcDir: '/',
  files: ['main.less'],
  destDir: 'appkit'
})
lessStyles = preprocess(lessStyles)

var sourceTrees = [app, styles, vendor, lessStyles]
if (env !== 'production') {
  sourceTrees.push(tests)
}

sourceTrees = sourceTrees.concat(findBowerTrees())

尝试构建此项目会产生错误：

$ broccoli serve
Serving on http://localhost:4200

        ^

Sounds like you're probably looking for broccoli-less-single instead of broccoli-less

From the README:

This plugin is designed to compile a single, primary input file into a single output file, with a tree of @importd dependencies. This differs from broccoli-less, which compiles each .less file individually into a .css file and doesn't support @imports or a single output file depending on multiple inputs.

As an aside, it looks like you're working with Ember.js -- if so, I would strongly recommend using ember-cli instead of rolling your own build pipeline. It easily supports less and provides lots of other features.
