title: EXDEV: cross-device link not permitted, rename '/usr/local/lib/node_modules/npm' -> '/usr/local/lib/node_modules/.npm-i9nnxROI'
body: <p>My builds keep failing on CircleCI with the error:</p>
  <pre class="lang-sh prettyprint-override"><code>EXDEV: cross-device link not permitted, rename '/usr/local/lib/node_modules/npm' -&gt; '/usr/local/lib/node_modules/.npm-i9nnxROI'
  </code></pre>
  <p>This happens before installing any library. Has anyone encountered this problem?</p>
