无法安装hubot – npm依赖关系未满足

在尝试部署hubot时，npm不断抱怨未满足的依赖关系。文档没有解释如何解决这个问题。

yum install npm --enablerepo=epel
yum install nodejs --enablerepo=epel
cd /opt
git clone https://github.com/github/hubot.git
cd hubot/
./bin/hubot --create acebot
npm install -g hubot coffee-script
...

coffee-script@1.6.3 /usr/lib/node_modules/coffee-script

packages.json文件包含依赖关系的列表，我认为它应该被自动解决。

"dependencies": {
    "coffee-script":      "1.6.3","optparse":           "1.0.4","scoped-http-client": "0.9.8","log":                "1.4.0","express":            "3.3.4"
  },

任何人都可以说明为什么npm不能安装hubot？

更新

我仍然不明白为什么它不工作，但运行npm安装之前运行npm install -g hubot咖啡脚本似乎已经过了这个错误。在发布答案之前，我需要进行验证

我不知道为什么它不起作用，但是我在Centos 6.3机器上安装保镖时遇到了类似的问题。 Yum已经从EPEL中继承了2个，但版本检测不起作用。 “sudo npm install -g inherited”安装了继承的版本，工作版本报告和bower / grunt-cli之后安装好。
