</pre><p><strong>NOTE: npm versions 1 and 2 will automatically install <code>peerDependencies</code> if
they are not explicitly depended upon higher in the dependency tree. In the
next major version of npm (npm@3), this will no longer be the case. You will
receive a warning that the peerDependency is not installed instead.</strong> The
behavior in npms 1 &amp; 2 was frequently confusing and could easily put you into
dependency hell, a situation that npm is designed to avoid as much as possible.</p>
