@Tjatse I added conf.js, like this.

[ohoroyoi]

options.pm2Conf = {
      DAEMON_RPC_PORT: path.resolve(options.pm2, 'rpc.sock'),
      DAEMON_PUB_PORT: path.resolve(options.pm2, 'pub.sock'),
      PM2_LOG_FILE_PATH: path.resolve(options.pm2, 'pm2.log')
    }

it was not empty and exists also. but still error message returns. Why do you think this is happening?
