title: Updating NPM on OpenShift
body: <p>Is it possible to update NPM to the latest version in an OpenShift application? (It comes with version 1.2.17 by default and I'm trying to upgrade to 1.4.x)</p>
  
  <p>Running the usual NPM command <code>npm update npm -g</code> returns a permission error;</p>
  
  <p><code>Error: EACCES, unlink '/opt/rh/nodejs010/root/usr/lib/node_modules/npm'</code></p>
  
  <p>And running <code>sudo npm update npm -g</code> gives a permission denied (<code>bash: /usr/bin/sudo: Permission denied</code>)</p>
