Command
> var Web3 = require(‘web3’);

Expected Behavior

I am not exactly sure what behaviour to expect.

Current Behavior

The output is:

Possible solution

Maybe being able to use testrpc will fix the issue. I'm not sure.

Did you set the NODE_PATH variable to node_modules? I did that and was able to load web3?
Contract can be loaded by
mycontract = new web3.eth.Contract(abi)
This is explained here.
https://ethereum.stackexchange.com/questions/22983/web3-eth-contract-is-not-a-function-when-making-contract
I am able to get through all this, but unable to use the new operator on contract.

I don't recall using NODE_PATH, I just followed the instructions in the LLL tutorials by Daniel Ellison.

I typed node first, then it prompted with >

jamesray1 picture jamesray1 on 2 Sep 2017

I edited my post.

jamesray1 picture jamesray1 on 2 Sep 2017

So according to that article:
I changed the web3 version to 0.20.0 in my package.json.

I then entered:
/opt/node/lib/node_modules/ethereumjs-testrpc/build/cli.node.js
in a new terminal window.
The output listed the testrpc v4.1.1, available accounts, private keys, HD wallet and "Listening on localhost:8545"
I then opened a new terminal, typed 

$ node
> var Web3 = require('web3');
undefined

Well it seems like undefined is not a good output, but moving on...

> var web3 = new Web3(new Web3.providers.HttpProvider(“http://localhost:8545"));
undefined
> var abi = [{"name":"identity","type":"function","constant":true,"payable":false,"inputs":[{"name":"input","type":"uint256"}],"outputs":[{"name":"","type":"uint256"}]}]
undefined
var Tutorial = web3.eth.contract(abi);

Did you try

Web3.eth.contract

Sorry I haven't got time to look at this now. I'll revisit if I want to use LLL. At the moment I'm finishing editing the yellow paper, so I'll probably go back to learning LLL for testing after that.

@jamesray1 thanks for reporting, but I'm not sure that this is a TestRPC issue? You can see how we instantiate a web3 contract from the solidity compiler's output in the ganache-core test suite. At the moment we use web3 ^0.19.1. I'd imagine this could easily be adapted to work from the LLL example you mentioned.

I recommend raising an issue with the web3 project if this is still a problem.

benjamincburns picture benjamincburns on 15 Nov 2017

I'm still not interested in using LLL (and thus trying to use web3 and testRPC) as I have other priorities related to focusing on research, e.g. scalability and Casper.

jamesray1 picture jamesray1 on 15 Nov 2017

Requires 'c' capital of contract. Additionally requires new keyword. So it should be

VotingContract = new web3.eth.Contract(abiDefinition)

The output

Thanks for the tip. I'll keep it in mind if I use LLL in future. Perhaps the code should be corrected in the LLL tutorials.

jamesray1 picture jamesray1 on 16 Nov 2017

Actually I think that my issue was caused by using ‘web3’ rather than 'web3'. Similarly "foo" should be used rather than “foo”.

jamesray1 picture jamesray1 on 16 Nov 2017

also a source of confusion web3.eth.contract(...) was from web3 0.x, while new web3.eth.Contract(...) is from the 1.0 beta. So if you're using the latest _stable_ version, it's the prior, or if you're on the beta (which I think they've tagged as latest so it's what you get when you npm install web3), it's the latter.

benjamincburns picture benjamincburns on 21 Nov 2017

help me，I use this ：
var abiToken = new web3.eth.Contract(abiAdress).at(aAddress);

end：
TypeError: (intermediate value).at is not a function
