title: Upgrading nativescript to 4.1.0
body: <p>At the time of writing, nativescript version on npm is <code>4.0.2</code>, but on github, there is a tag for <code>4.1.0</code>. I would like to install <code>4.1.0</code>, since some bugs have been fixed there.</p>
  
  <p><code>tns update 4.1.0</code> returns <code>Could not update the project!</code> error and <code>npm install -g nativescript@4.1.0</code> returns <code>No matching version found</code> error. </p>
  
  <p>How can I upgrade?</p>
