title: How to find nodejs version
body: <p>I installed nodejs first with nvm but it didn't work as I expected.
  When I installed it with LTS version <code>sudo yum -y install nodejs</code>, it worked but I'm not able to find the version of node.</p>
  
  <pre><code>node -v
  -bash: /root/.nvm/versions/node/v8.11.3/bin/node: No such file or directory
  </code></pre>
  
  <p>I tried to remove nvm but still getting the same message.</p>
