title: npm install resulting in 'ENOENT: no such file or directory'
body: <p>I've installed Node.js for Windows and I'm trying to install a package via npm. The command prompt is in the directory of the project (C:\Users\username\Desktop\NodeTest), which contains a single helloworld.js file. Upon typing 'npm install express', I receive the following error:</p>
  
  <p><code>ENOENT: no such file or direcotry, open 'C:\Users\username\package.json</code></p>
  
  <p>I'm attempting this from a clean install and cmd is running as admin.</p>
  
  <p>Any ideas?</p>
