如何通过brocfile.js中传递param {oftrite:true}

ember-cli: 0.2.5,
ember-cli-less: 1.3.3,

Merge error: file assets/mobile.css.map exists in mobile/tmp/caching-writer-dest-dir_ZcaW3C.tmp and /mobile/tmp/caching-writer-dest-dir_E4iROO.tmp
Pass option { overwrite: true } to mergeTrees in order to have the latter file win.

，因为上一个链接中提到的方法都没有。我选择修改ember-cli-cli-beack：

node_modules/ember-cli-less/node_modules/broccoli-merge-trees/index.js

我更改了行：

function TreeMerger (inputTrees, options) {
  if (!(this instanceof TreeMerger)) return new TreeMerger(inputTrees, options)
  if (!Array.isArray(inputTrees)) {
    throw new Error('Expected array, got ' + inputTrees)
  }
  this.inputTrees = inputTrees
  this.options = { overwrite: true } // <- This line
}

Mergetrees模块具有overwrite的选项。

在此处记录：https：//github.com/broccolijs/broccoli-merge-trees-trees#options

这是一个示例：

return new MergeTrees([app.toTree(), fonts], { overwrite: true });

如果您使用的是Mac，可以尝试find . -name '.DS_Store' -type f -delete？

我有一个类似的问题，我能够通过删除重复文件来解决。

错误消息

Build failed.
