Ember：brocolli插件因快速入门而失败

Question

我试图在https://guides.emberjs.com/v2.16.0/getting-started/quick-start/运行ember快速入门。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我的项目看起来像截图。我可以轻松地在USB密钥（E :)上运行所有内容。

E：nodejs上的便携式节点文件夹如下所示：

我已将npm前缀设置为

$ npm config set prefix E:/nodejs

按照我的指示：

$ ember serve

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

The Broccoli Plugin: [ConfigReplace] failed with:

我怎样才能使这个工作？
