title: The term 'Install-Module' is not recognized as the name of a cmdlet, function, script file, or operable program
body: <p>Installing posh-git - see here <a href="https://github.com/dahlbyk/posh-git" rel="nofollow">https://github.com/dahlbyk/posh-git</a></p>
  
  <p>If I've just installed PsGet installed then running:</p>
  
  <pre><code>Install-Module posh-git
  </code></pre>
  
  <p>works fine.</p>
  
  <p>But if I close and re-launch Powershell then I get:</p>
  
  <pre><code>The term 'Install-Module' is not recognized as the name of a cmdlet, function, script file, or operable program.
  </code></pre>
  
  <p>when I try and run it.</p>
  
  <p>Any idea why?</p>
