Require failing for some node.js modules

[balupton]

Originally I thought this was a npm issue, but the NPM author believes it is a coffee-script issue.

Hey Isaac,

So I've published my module buildr which uses another one of my modules called cson, but when I try to run buildr I get Error: Cannot find module 'cson'. Here is the full log. This really has me scratching my head... :/

$ node -v

$ npm -v

$ npm -g install buildr

This is a coffee-script bug. Looks like it doesn't use node's module lookup when you use the "coffee" command.

@jashkenas?

npm explore -g buildr
node
require("coffee-script"); require("cson")
{ parseFile: [Function], parse: [Function], stringify: [Function] }

$ coffee
coffee> require("cson")

I believe this is a duplicate of #1035, module.paths in the REPL.
