我在Windows 8.1上，有流浪汉，Cheffile，一切正常。
现在我在做：
npm install -g ember-cli ，没关系。
但是当我这样做时：
在vagrant文件夹中的ember new sample （我在Windows中可以查看的文件夹）我收到此错误：
version: 1.13.8
Could not find watchman, falling back to NodeWatcher for file system events.
Visit http://www.ember-cli.com/user-guide/#watchman for more info.

我在流浪汉的最后一个方框（今天我做vagrant box update）和node -v说我： v0.12.7 和npm -v说： 3.3.3
怎么办？
我尝试了： sudo（而不是sudo）npm cache clean 以及 sudo 用于其他所有命令。没什么，同样的错误。
含义： npm ERR! tar.unpack untar error ???
