接收package.json的解析错误.验证为有效的json

我正试图创建我的第一个yeoman生成器，当我运行yo创建我的项目时，我遇到了以下错误。

npm ERR! install Couldn't read dependencies
npm ERR! Darwin 14.0.0
npm ERR! argv "node" "/usr/local/bin/npm" "install"

我已经使用jsonint验证了package.json文件。我还执行了npm缓存清理。package.json文件可以在这里找到：https://github.com/dereksnow/generator-simple-stylus/blob/master/package.json

有什么建议吗？
