title: express jade upgrade to latest throwing error
body: <p>My app was running fine with express, jade etc.
  Today when I upgraded this to latest express and jade, using <code>npm update express jade</code>, it started throwing the following error when i try to access the site. Is it expecting a package.json ?</p>
  
  <p>I am not using package.json, but rather using NODE_ENV to point to C:\Personal\software\nodejs\NODE where all my node modules are installed.</p>
