I'm going to revert and disable the test on chromeos. +achuith for longer term fix (maybe move this module to CrOS? Switch to isolate? :))

Yup, we have a bug to move this module to chromeos; just need to find someone to work on it.

I don't quite understand why these fail on chromeos but not on other platforms? 

The following revision refers to this bug:

Yeah, I don't either. The only thing I can think of would be that sys.prefix or sys.real_prefix is some subset of /usr/local/telemetry/src/third_party/catapult/telemetry/telemetry/internal/testing/dependency_test_dir/other_animals/cat/cat

Which has a lot of telemetry animals and cats...

+iannucci@, this must be same as 818054?

yes, I had un-duped them to keep this one open specifically re: cros, though I didn't close the other one yet.

Getting back from leave; I'm not working on this so marking available (lmk if this needs my input though).
