Error requiring sol files with interface imports

When using web3.require to compile solidity contracts with the following
web3.require('./validators/OwnedSet.sol')
I'm get the following error:
screen shot 2018-04-05 at 18 07 08

The OwnerSet.sol contract imports an interface contract which may be causing this error. Upon investigation, it looks like web3-require.js does a check on the bytecode and throw error if it is not in the correct format. In my case, the error is caused by the empty bytecode on interface methods.

However, this seems to be the expected output when compiling an interface. I tried compiling the contract with the following command
solc --combined-json abi,bin ./contracts/validators/OwnedSet.sol > out.json
And I get the following output:

{

    "./contracts/validators/OwnedSet.sol:OwnedSet": {

The workaround for me right now is to temporary comment out the throwOnAmbiguousPlaceholders check at web3-require.js:54. Looks like we may need to add a conditional check to allow for empty bytecodes to support interfaces?

Please see the source for the contracts attached as txt files:

Add support for node_modules imports

Similar to what truffles allow, it would be nice to be able to import contracts that are located in the node_modules folder rather than having to copy them over inside of the contract path.

ex:

import "@appliedblockchain/trufflib/libraries/Sig.sol";

where "@appliedblockchain/trufflib" is an installed node module

Make cross-platform

There are probably some other concerns, but a couple of notable ones:

  1. Include apt or similar instructions in the readme
  2. Code like this:
const { web3, accounts } = require('../lib/web3')({
  root: `${__dirname}/../contracts`
})

should be changed to:

const { join } = require('path')

const { web3, accounts } = require('../web3')({
  root: join(__dirname, '..', 'contracts')
})
