安装Gitbook过程出错～? 400 报错

大家，我现在在Ubuntu13.04下安装GitBook出错。已经排除被墙的原因。现在是这样的我执行

$ npm install gitbook -g

npm ERR! error installing gitbook@0.2.4
npm ERR! error rolling back gitbook@0.2.4 Error: ENOTEMPTY, rmdir '/usr/local/lib/node_modules/gitbook'

然后我执行node -v   显示：v0.10.26

我就不明白了，npm里是0.6.19，而我的环境里是0.10.26。

谢谢。
