Watchman errors with exit code=3221225781

[BrennanR]

I'm trying to use relay-compiler on windows, which seems to depend on watchman. I've followed the steps outlined here: #19 for windows support, yet I'm still running into this error. Windows, node, and npm version can be seen below.

> relay-compiler --src ./assets --schema schema.json

HINT: pass --watch to keep watching for changes.

      throw er; // Unhandled 'error' event

Any ideas as to what the issue might be?

What happens if you run watchman --no-pretty get-sockname from a command prompt?

Anything useful in the watchman logs? https://facebook.github.io/watchman/docs/troubleshooting.html#where-are-the-logs

My best guess is that you installed the npm watchman package globally. That's not the same thing as the facebook watchman service, despite the unfortunate naming clash.
