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!
