title: Couldn't install dependencies while setting up strapi project
body: <p><code>npx create-strapi-app my-project --quickstart</code>
  I am executing this command and it is trying to download certain libraries from github using npm. Due to security reasons the servers are not allowed access to github, so it is not able to download libraries like <em>libvips</em>. Is there any other way to setup a strapi project so that it could get libraries from any other source ?
  Here's the error snippet</p>
  <pre><code>npx: installed 91 in 18.847s
  Creating a new Strapi application at /home/centos/my-project.
  
  Creating a quickstart project.
