When compiling my contract code in truffle I receive this error:

Error parsing zeppelin-solidity/contracts/token/ERC20/StandardToken.sol: ParsedContract.sol:33:18: ParserError: Expected token Semicolon got 'LParen' emit Transfer(_from, _to, _value);

I am running through this guide: https://maksimivanov.com/posts/ethereum-react-dapp-tutorial

I download zeppelin-solidity's files, and copied and paste the code. I don't understand why this wouldn't be working. I tried changing the pragma to 4.21 because that is what the standardToken's solidity code is written in. How do I fix this problem?

    What version of truffle are you using? Try updating to the latest that requires solc 0.4.23.

I updated to truffle 4.1.8 and this fixed my issue immediately. I thought I had updated, but I didn't update truffle globally.
