This was an environmental issue with a previous install of pcre on this machine and I was able to resolve it.

Here are details in case anyone else encounters it:

This was on a box that had never had Homebrew installed on it, but did have pcre installed in /usr/local and other places. When I installed Homebrew, brew doctor warned about these pcre files, and since I had previously noticed that pcre is used for React Native, I proceeded to manually remove all of the pcre files that brew doctor reported, and then proceeded with brew install node and brew install watcher.

Given that this appeared to be a watcher issue, I tried uninstalling watcher, and reinstalling it. At that point, brew had me try brew link pcre and pointed out additional existing pcre files that it was having problems with, and I addressed each of those, with the offending files/directories including

/usr/local/bin/pcre-config
/usr/local/bin/pcregrep
/usr/local/bin/pcretest
/usr/local/share/doc/pcre
/usr/local/share/man/man1/pcre*
/usr/local/share/man/man3/pcre*

After cleaning up these additional leftover files, and successfully installing watchman, I then used brew to uninstall node, pcre, and watchman and clean reinstall node and watchman.

After all of this, and in a fresh clone of react-native, things worked on this box, including running the Movies app in Xcode.

I'm glad it's working now. I'm glad we put a timeout on that so it doesn't fail silently :)

Is there any way we can add a warning so that other people don't fall into the same trap?

I doubt it's typical problem, it's the first time I've heard of it with watchman. And a lot of people are using it through my sane module. If it comes up again, will have a deeper look.

FWIW, I had installed pcre binaries on this particular machine a few years ago for some esoteric thing I can't even recall the details of. I don't usually install binaries like that. That, combined with the fact that I hadn't been using Homebrew is probably a fairly rare combination. Homebrew itself tried to warn about it, so I had enough clues to go on.

The existence of the timeout is useful, IMHO. If it had somehow additionally indicated something derailing in a way that pointed a finger at pcre, that would probably have been helpful and I would have sorted it sooner, but to be honest, I didn't lose a lot of time on this and was able to sort it out pretty quickly anyway.

I think running watchman from terminal could give a clue

I'm not sure how it all fell into place, but I ended up in the same place as @mfikes. I followed his above steps and was able to resolve the issue.

The odd part is that pcre appeared to have been installed by homebrew (it came up in brew ls). I was also able to run watchman from the command line in other scenarios and it would work, it was only not working for react-native! Anyway, uninstalling pcre and doing a fresh install of node and watchman resolved my issue. Thanks for documenting how you fixed it @mfikes!
