title: I've installed angular cli but its showing not recognized in cmd
body: <p>Actually I've installed <code>Nodejs</code>, then <code>npm</code>, then <code>angular cli</code> properly (afaik). But in windows cmd and in git bash, its showing "ng --version" as:</p>
  
  <blockquote>
    <p><code>ng</code> is not recognized as an internal or external command,
    operable program or batch file.</p>
  </blockquote>
  
  <p>from windows command prompt</p>

  <p>but when i try this command with node command prompt, it showing the ng version.</p>

  <p>Because of this, i cannot use ng serve. Also i've tried to install bower and gulp. Getting the same "not recognised" error for both of them. Help to solve this.</p>
  
  <p>Thanks and Regards,
