I'm learning about ethereum and smart contracts and I have a simple contract that stores a string. I'm trying to use web3js to change that string. I'm having trouble following the instructions from this answer https://ethereum.stackexchange.com/a/12932. This works fine when I'm in the geth console but when I try to make a js script or use the node console it's like .at doesn't exist. This is my output.
> var contractAbi = new web3.eth.Contract(abi); > var myContract = contractAbi.at(contractAddress); TypeError: contractAbi.at is not a function at repl:1:30 at sigintHandlersWrap (vm.js:22:35) at sigintHandlersWrap (vm.js:73:12) at ContextifyScript.Script.runInThisContext (vm.js:21:12) at REPLServer.defaultEval (repl.js:340:29) at bound (domain.js:280:14) at REPLServer.runBound [as eval] (domain.js:293:12) at REPLServer.<anonymous> (repl.js:539:10) at emitOne (events.js:101:20) at REPLServer.emit (events.js:188:7) at REPLServer.Interface._onLine (readline.js:232:10) at REPLServer.Interface._line (readline.js:583:8) at REPLServer.Interface._ttyWrite (readline.js:860:14) at REPLServer.self._ttyWrite (repl.js:612:7) at ReadStream.onkeypress (readline.js:119:10) at emitTwo (events.js:106:13) at ReadStream.emit (events.js:191:7) at emitKeys (internal/readline.js:389:14) at next (native) at ReadStream.onData (readline.js:970:36) at emitOne (events.js:96:13) at ReadStream.emit (events.js:188:7) at readableAddChunk (_stream_readable.js:176:18) at ReadStream.Readable.push (_stream_readable.js:134:10) at TTY.onread (net.js:547:20)
Has anyone had this problem and knows of a fix?
