gyp build error on macOS 10.14

[chrissimpkins]

I attempted to build on macOS 10.14.4 with:

Python 2.7.16

Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.5.0
Thread model: posix

and received the following Exception:

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'groups'

The regex change that was proposed in node-gyp (issue report) fixes this and the compile completes without issues when I edit the gyp submodule.

Does anyone here have a Chromium dev environment and Chromium submitter permissions set up to test and propose this in the gyp project?
