title: CasperJS on NodeJS - cannot find module casper
body: <p>Im currently trying to get Casperjs working on my Nodejs discord bot. But everytime i want to test it (with the example provided by the casperjs documentation)</p>
  
  <pre><code>var casper = require("casper").create();
  
  casper.start('http://casperjs.org/', function() {
      this.echo(this.getTitle());
  });
  
  casper.thenOpen('http://phantomjs.org', function() {
      this.echo(this.getTitle());
  });
  
  casper.run();
  </code></pre>
  
  <p>Everytime i wanted to start real coding im confroted with "cannot find module casper". How can i solve this ?</p>
  
  <p>i already tried some solutions from stackoverflow, but the all seem to be outdated/ i used them wrong. </p>
  
  <p>i also read that i need phantomjs for casper (so i did npm install phantom) but dont know if i need to do more with it. Later on i also read that casper can be used alone now. I followed the Quickstart guide on the casper.js website but didn´t manage to make it work.</p>
  
  <p>Thank you for your Answers !</p>
