How to solve this?

Answer 1

Have you specified the network in the configuration file? Your truffle.js file should look something like this:

module.exports = {

  networks: {

    development: {

      host: "localhost",

      port: 8545,

      network_id: "*" // Specify the network here

    }

  }

};

Answer 2

You have to mention on which network you want to migrate the contract. After specifying the network, it will work fine. You have to add the network in the truffle.js file which you will find in the directory where you have created the truffle project.
