对 CentOS 6.4 的依赖破坏：可以安装 nodejs 但不能安装 npm

我正在使用带有 EPEL 存储库的全新安装的 CentOS 6.4 (x86-64)。

$ yum install nodejs
...
$ node -v
v0.10.5

到目前为止一切顺利，但是当我尝试安装时npm，我会收到以下错误消息：

$ yum install npm

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

完整的输出相当大： http ://pastebin.com/raw.php?i=Ce3ZJsEB

我应该怎么办？--skip-broken解决方法似乎不是正确的解决方案。

这是输出yum repolist：
