npm WARN deprecated npmconf@2.1.2: this package has been reintegrated into npm and is now out of date with respect to npm : <p>I am installing node.js on a CentOS 7 server, and am getting the following error when I try to install yeoman:  </p>

<pre><code>npm WARN deprecated npmconf@2.1.2: this package has been  
reintegrated into npm and is now out of date with respect to npm
</code></pre>

<p>The install of yeoman seems to otherwise work correctly.  Is there something that I can do to avoid this warning?  What are the implications of leaving it unhandled?  </p>

<p>Here is the rest of the first part of the terminal output from the yeoman install:  </p>

<pre><code>[root@localhost ~]# npm install -g yo
