@benkomalo I can reproduce this if I don't have watchman
installed.
from react-native.
Ah, interesting. Thanks, @mfikes. If I manually install watchman
that gets around that issue (though I'm now seeing Watcher took too long to load
, but I can debug that a little more before filing a separate issue for it).
Is there a reason watchman
isn't listed in packages.json
?
from react-native.
@benkomalo I had Watcher took too long to load
and for me the root cause was a botched pcre
installation. See #20
I can't answer the question regarding packages.son
(I'm not with Facebook.) The only reason I knew to install it is the recommendation in the main README.md
.
from react-native.
Cool. Thanks, again @mfikes. I'll assume there's a good reason for keeping it separate from packages.json
then. Will close out for now.

I don't think we can install watchman automatically via npm.
from react-native.
I was wondering if this is actually the "node file watching bug" referenced in Step 5 of the Requirements section in README.md
. If so, perhaps a future README.md
could give a sample line from the endless stream, making it a little easier for devs to know when watchman
is needed.
from react-native.
I think we should make it a mandatory dependency. We check for it and exit with a useful error message on how to install it if it's not available. Thoughts?
from react-native.
My view: While Ben's environment had a few items that are a little older, mine is completely up-to-date (OS X 10.10.2, Node v0.10.36 via brew, and npm version 2.3.0 via brew). So If a lot of users are like me, and if my ability to reproduce this is deterministic (it appears to be), then perhaps watchman
should be required instead of recommended.
from react-native.
We can have brew install watchman
in the npm postinstall script.
from react-native.
OK, after chatting with @ericvicenti I think the ideal thing to do here is to have a log message with a link to installation directions, because brew
is 1) OS X specific and we'll soon have other platforms 2) it feels weird to install native binaries with brew via npm install.
