'Unhandled Promise Rejection Warning' after running command

[samwrigley]

When running any stacklint command, I get the following error after confirming 'Yes' to 'Are you sure you want to continue?':

(node:84425) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: fs.copyFileSync is not a function (node:84425) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Node: v8.1.3
NPM: v5.5.1

Strange. I don't get any errors. Could you try upgrading node/npm?

Node: 8.7.0+
NPM: 5.6.0+

Hi @m2de, upgrading Node to v9.4.0 fixed the issue.
