Cannot find module 'commonjs-utils'? - json

Question

I'm trying to get a JSON schema validator up and running per:
http://davidwalsh.name/json-validation
I installed node via brew, and installed commonjs-utils, but can't figure out how to require it:
bash-3.2$ npm install commonjs-utils
commonjs-utils#0.1.1 ./node_modules/commonjs-utils
bash-3.2$ node
> require('commonjs-utils')
Error: Cannot find module 'commonjs-utils'

Any ideas?

Answer 1

Try this:
require('json-schema');

Answer 2

I tried the same code from "David Walsh" (link) and I got the same error. In my case, I can see the validation function works after changing the line 6 of the original code as the following.
[OLD] var validate = require('commonjs-utils/json-schema').validate;
[NEW] var validate = require('commonjs-utils/lib/json-schema').validate;
