I try to call


on truffle console. However I got an error:

TypeError: Cannot read property 'sha3' of undefined

Does this mean web3.utils.sha3 has not supported yet?


It appears you're trying to use the web3.js 1.0 syntax of web3.utils.sha3(string) but the latest version of truffle actually uses web3 0.20.1 which has the syntax web3.sha3(string [, options]). Try that instead.
