Answer 1

Per the line

'pg_config' is not recognized as an internal or external command

I just need to install PostgreSQL before trying to

npm install pg

Answer 2

Have you checked out the installation instructions for node-gyp?

https://github.com/TooTallNate/node-gyp#installation

I recently had issues with node-gyp on Windows also while trying to install a separate module that depended on it. Make sure you have each of the items installed that it requires. Pay attention to this part specifically:

For 64-bit builds of node and native modules you will also need the Windows 7 64-bit SDK If the install fails, try uninstalling any C++ 2010 x64&x86 Redistributable that you have installed first.
