Error: dlopen ... Symbol not found ...

[semireg]

I'm seeing a error when requiring/importing. This is on a Mac, 10.13.6, Electron 3.0, Node 10.11.0.

Everything was working fine... now this. I've tried reverting to a different commit on my project and I'm still seeing this issue. Has anyone encountered it before? Googling for similar issues isn't yielding helpful results. I wish I knew how I ended up breaking my build... 👎

  return process.dlopen(module, path.toNamespacedPath(filename));

Doh! Disregard. ReadPath is a function I added for windows and now I'm trying to build on a Mac. I have to add stubs... or conditional compilation.
