Ember构建失败

Question

我尝试在本地运行Ember项目：https://github.com/cosmicjs/ember-real-estate-website?files=1。我使用gchar-bash作为win7中的终端使用pycharm 2017。我安装了npm，node和ember。在pycharm中，我的项目看起来像截图。

切换到cosmic-real-estate文件夹后：

  $ ember build

  Running without permission to symlink will degrade build performance.
  See http://ember-cli.com/user-guide/#windows for details.

  Build failed.
  The Broccoli Plugin: [Funnel: Funnel: index.html] failed with:
