title: Running 'npm install' causes a 'npm ERR! code E401'
body: <p>I'm trying to get a co-worker set up so that she can run 'npm install'  I'm able to run it fine on my machine.</p>
  <p>When she runs the command, it starts and appears to be running successfully for several minutes - and then dies at the very end with:</p>
  <p>npm ERR! code E401
  npm ERR! Unable to authenticate, need: BASIC realm=&quot;Sonatype Nexus Repository Manager&quot;</p>
  <p>I know that she has a recent version of nodejs installed.</p>
  <p>I also know that she has access to our nexus repository and should have all the correct permissions.  I'm also a little surprised that it appears to be running fine and then dies right at the end.  I would think if there was an authentication error she would get it right away.</p>
  <p>Any suggestions?</p>
  <p>Thanks</p>
