I'm trying to deploy a node.js application to heroku, and get an error:
Installing dependencies with npm
npm ERR! Error: No compatible version found: express@'>=3.0.0'
When deploying from Cloud9. Does heroku support express 3.0?
You probably haven't specified what version of Nodejs your app supports.

By default, it uses Node 0.4.7, which will not work with express 3.x. I think you will need at least Node >= 0.5.0.
