iron-node profiling fails with multiple errors

radiovisual commented 8 years ago

Description

When following the profiling instructions in maintaining.md:

$ iron-node node_modules/ava/profile.js <test-file>

I get multiple runtime errors (see below). If it helps, I ran the profiler against the AVA tests in https://github.com/sindresorhus/generator-nm

Error Message & Stack Trace

Here is the text from the screenshot above:
