Error with subprocess.CalledProcessError: Command

Any ideas on why this is happening?

Here is the input:

    'build-atom-shell': {
      tag: 'v0.19.5',
      nodeVersion: '0.18.0',
      config: 'Debug',
      buildDir: './temp',
      projectName: 'predixgo',
      productName: 'PredixGo'
    },

Here is the output:
