Node.JS: Can't use require to parse .json file in REPL

So I'm trying to parse a config.json file from the REPL. The file is: app/config/config.json and I'm running the REPL from app/.

In the REPL if I try to require the file, the REPL doesn't execute, instead waiting for more input:

$ node
> var config = require('./config/config.json');
...

I'm sure it can be done, but I'm not sure what I'm doing wrong: http://stackoverflow.com/a/9804910/1027966

Turns out you cant use Node.js' require to parse JSON if the JSON is invalid. That behavior I witnessed occurs when the parsed JSON is invalid.
