Truffle 2.0 uses a different folder structure. The config directory has been replaced with a migrations directory. To get this project to deploy: 1) mkdir conference 2) cd conference 3) Run truffle init 4) cd contracts. If you do an ls, you will notice three Solidity files (ConvertLib.sol, MetaCoin.sol and Migrations.sol) I deleted ConvertLib.sol and MetaCoin.sol. You need Migrations.sol. Do not edit this contract. Create a new file and dopy the conference.sol contract from this repository into this file and save as Conference.sol. 5) cd ../migrations and do an ls. You should see two files (1_initial_migration.js and 2_deploy_contracts.js) These are crucial to deploying the truffle dapp. They need to be numbered in sequence. The 1_initial_migrations file deploys the Migrations contract and the 2_deploy_contracts deploys all your other contracts. 2_deploy_contracts needs to be edited so that it knows about your Conference contract. Edit this file - here's how mine looks: module.exports = function(deployer) { deployer.deploy(Conference); }; 6) truffle compile 7) truffle migrate 8) truffle build and everything should deploy without errors.
Where I am current stuck is when I run truffle test, I get Contract: Conference 1) Initial conference settings should match
No events were emitted 2) Should update quota No events were emitted 3) Should let you buy a ticket No events were emitted 4) Should issue a refund by owner only No events were emitted
0 passing (1s) 4 failing
1) Contract: Conference Initial conference settings should match:

2) Contract: Conference Should update quota:

The third-step for deploying a smart contract is
add the contract name to "contracts" in config/app.jsonBut I am using Truffle version 2.0.1 and
truffle initdoes not create a 'config' directory in my project directory.
