1. Warning: Couldn't find environment undefined.

2. truffle deploy is now giving me [Error: Server error: File "testrpc.py", line 232, in eth_compileSolidity | KeyError: 'solidity’]

That’s an probably an issue with your Ethereum testrpc where it doesn’t send compile errors through the RPC. Check out the testrpc output - it should tell you why the contract didn’t compile. If it doesn’t give you a compile error, it means it can’t find solc, the solidity compiler.

• To install solc: https://github.com/ethereum/cpp-ethereum/wiki/Building-on-MacOS (see right column for other platforms)
• Then you can use https://github.com/ConsenSys/testrpc to run a testrpc
