Error: Could not find zeppelin-solidity/contracts/crowdsale/Crowdsale.sol from any sources

[k06a]

We are using zeppelin-solidity package.

Error: Could not find zeppelin-solidity/contracts/crowdsale/Crowdsale.sol from any sources; imported from /home/travis/build/bitclave/crowdsale/coverageEnv/contracts/BonusCrowdsale.sol

Hi @k06a.
If you're doing this in your solidity files:

import "zeppelin-solidity/contracts/crowdsale/Crowdsale.sol";

Do this in your .solcover.js config file

module.exports = {
  copyNodeModules: true
}

At the moment we don't automatically copy the modules because it can take a long time and this is only a problem when importing solidity into solidity from npm installed packages. Solidity's import directive doesn't recursively search outside the parent directory the way JS import or require does.

[k06a]

@cgewecke thanks for instant reply! I'll try in a few minutes.

@cgewecke having a new issue: https://travis-ci.org/bitclave/crowdsale/builds/289719158

I was partially copied from truffle.js config:

require('babel-polyfill');

module.exports = {
    networks: {
        development: {
            host: "localhost",

            network_id: "*",

        }
    }
};

[cgewecke]

See #136.

@cgewecke what is coverage network? Sorry, I'm really new to JS/Solidity.

[k06a]

@cgewecke does it mean to add this to truffle.js?

require('babel-register');
require('babel-polyfill');

module.exports = {
    networks: {
        development: {
            host: "localhost",
            port: 8545,
            network_id: "*",
            gas: 6000000
        },
        coverage: {
            host: "localhost",
            port: 8545,
            network_id: "*",
            gas: 6000000
        }
    }

Added pkill -9 testrpc step before coverage step in .travis.yml

[k06a]

Added testrpcOptions to increase gas limit to .solcover.js:

require('babel-register');
require('babel-polyfill');

module.exports = {
  copyNodeModules: true,
  testrpcOptions: '-l 6000000'
}

Reference: https://www.npmjs.com/package/solidity-coverage

[k06a]

Right now using following configuration of truffle.js:

require('babel-register');
require('babel-polyfill');

module.exports = {
    networks: {
        development: {
            host: "localhost",
            port: 8545,
            network_id: "*",
            gas: 10000000
        },
        coverage: {
            host: "localhost",
            port: 8545,
            network_id: "*",
            gas: 10000000
        }
    }
};

Content of .solcover.js:

require('babel-register');
require('babel-polyfill');

module.exports = {
  copyNodeModules: true,
  norpc: true
}

Content of .travis.yml:

sudo: required
dist: trusty
language: node_js
node_js:
  - '7'
install:
  - npm install -g truffle
  - npm install -g ethereumjs-testrpc
  - npm install
script:
  - npm test
before_script:
  - scripts/rpc.sh > /dev/null &
  - sleep 5
after_script:
  - npm run coverage && cat coverage/lcov.info | coveralls

Content of rpc.sh:

#!/usr/bin/env bash
testrpc -l 10000000

I am having problems with gas:

  1) Contract: Crowdsale:  "before all" hook:
     Error: VM Exception while processing transaction: out of gas

https://travis-ci.org/bitclave/crowdsale/builds/289971276

10M of gas should be enough!

Hi. Please look at the link to the zeppelin truffle config in #136 and copy the values in their coverage network. They are the same values recommended in the README doc as well. I think your babel imports should be made there too. The solcover config is only for coverage options.

Also just try letting solidity-coverage launch its own testrpc in travis. Don't run one yourself unless you have to, and follow the recommendations in the FAQ if you do. On Oct 19, 2017 6:38 AM, "chris gewecke" <christophergewecke@gmail.com> wrote:
