Have you specified a network on truffle.js?

Add the following to truffle.js to deploy locally to testrpc (First run testrpc on another console tab):

module.exports = {
  networks: {
    development: {
      host: "localhost",
      port: 8545,
      network_id: "*", // Match any network id
      gas: 4500000
    }
  }
};

This solved the problem for me. I think in previous Truffle version the development network was there by default? If not, there is a comment in the file

  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!

Thanks
