I am unsure why I keep getting this error:
Using network 'development'.
Running migration: 2_deploy_contracts.js
Deploying Token...
... 0x02f042faec7c36c74bb0df346ccda5339ea653eb55c79996a3af81a9be055992
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: The contract code couldn't be stored, please check your gas amount.
I am simply trying to deploy the standard ERC20 example from Consensys.
From what I understand this error occurs when a function is abstract, but I can't seem to find any of those, unless I get my definition of abstract wrong.
The ProToken contract inherits from Token one, which just follows ERC20 standards, what could be wrong ?
contract ProToken is Token {
mapping (address => uint256) balances;
mapping (address => mapping (address => uint256)) allowed;
uint256 constant MAX_UINT256 = 2**256 - 1;
function transfer(address _to, uint256 _value) returns (bool success) {
require(balances[msg.sender] >= _value && balances[_to] + _value > balances[_to]);
balances[msg.sender] -= _value;
balances[_to] += _value;
Transfer(msg.sender, _to, _value);
return true;
}
function transferFrom(address _from, address _to, uint256 _value) returns (bool success) {
uint256 allowance = allowed[_from][msg.sender];
require(balances[_from] >= _value && allowed[_from][msg.sender] >= _value && balances[_to] + _value > balances[_to]);
balances[_to] += _value;
balances[_from] -= _value;
if (allowance < MAX_UINT256) {
allowed[_from][msg.sender] -= _value;
}
Transfer(_from, _to, _value);
return true;
}
function balanceOf(address _owner) constant returns (uint256 balance) {
return balances[_owner];
}
function approve(address _spender, uint256 _value) returns (bool success) {
allowed[msg.sender][_spender] = _value;
Approval(msg.sender, _spender, _value);
return true;
}
function allowance(address _owner, address _spender) constant returns (uint256 remaining) {
return allowed[_owner][_spender];
}
}
contract Token {
/// total amount of tokens
uint256 public totalSupply;
/// @param _owner The address from which the balance will be retrieved
/// @return The balance
function balanceOf(address _owner) public constant returns (uint256 balance);

I Had the same Issue, Downgrading Truffle worked for me fine.
