v1.12.2 causes cli issues

[blackdynamo]

I am not using the typescript option. Things worked fine in v1.12.0.

> ./bin/run

module.js:550
    throw err;
    ^

+1 it appears that this was introduced in #70. Hoping to find someone in the Gitter chat to help triage.

In case it helps, we're using typescript and see the error as well

I reported this earlier here: oclif/oclif#204 and will close it.

Fixed by #72.
