Answer 1

Make sure you have mongoose installed locally (in the folder node_modules that is on the same level with your server.js file) OR that it's installed globally.

If that's not the case please paste the error message so we can determine exactly what's the root of the problem.

Answer 2

Add mongoose to your package.json file as a dependency, then run "npm install" from the shell. Should install mongoose and anything else you need. -fs
