[DominicKramer]

Environment details

• OS: OS X
• Node.js version: v6.9.4
• npm version: 3.10.10
• google-cloud-node version: @google-cloud/error-reporting@0.1.0

Steps to reproduce

Provided the NODE_ENV environment variable is not set to production, the following code should print a message to standard out stating that the NODE_ENV environment variable needs to be set to production or the ignoreEnvironmentCheck needs to be set to true. However, nothing is printed to standard out.

var errors = require('@google-cloud/error-reporting')({
  serviceContext: {service: 'my-service'}
});
errors.report(new Error('Something broke!'));
