Packager fails on macOS 10.12 Sierra #9309
Description
I have upgraded to the macOS Sierra beta yesterday, and the React Native Packager seems to fail. I've tried to reinstall the dependencies, but no use.
The output of the packager is this:
[11:45:02 AM] <START> Building Dependency Graph
[11:45:02 AM] <START> Crawling File System
[Hot Module Replacement] Server listening on /hot
React packager ready.

The only reference to that specific error I have found is this old issue on the Node 0.10 repo's. I have tried the 'fix' in that topic, namely increasing the open file references limit. That didn't work.
The issue occurs on both Node 4.4.7 and 6.3.1, on macOS Sierra 10.12 on a MBP 2015 15". Does anyone know what is going on here?

Credit to @passwd for figuring this out
We were able to get it to work by increasing the max file limit and moving to watchman v4.6.0
here are the steps we followed:
1. increase max file limt
2. upgrade to watchman 4.6

@mc-lean you're the best!!!
goldenice commentedon Aug 12, 2016
@mc-lean Nice! :)
Are there any plans to update watchman in the RN-repo so RN works out-of-the-box again?
mc13an commentedon Aug 12, 2016
@goldenice I would guess that it is. Sierra is due out in September so I would think they would plan to support it out of the box soon

@mc-lean Thanks 👍

System doesn't report the updated value when i run
sysctl kern.maxfiles(reports 300k) but upgraded to watchman 4.7.0 withbrew install watchmanand it seems to workmonder commentedon Sep 13, 2016
@jalmaas value updates only after reboot. Worked for me on GM.
But indeed, just updating to
watchman4.6.0+ seems to be enough.jalmaas commentedon Sep 13, 2016
it didn't update after reboot here

React Native works fine with relatively up-to-date software. These are the settings that are working for me:

i ran brew install automake but still can't compile watchman
artforlife commentedon Oct 30, 2016
@sammosampson What errors are you getting?
artforlife commentedon Oct 30, 2016
After updating to OSX Sierra and XCode 8.1, I cannot compile any of the React-Native projects. I get the error that the OP had. At this point, I have not been able to resolve it. You may consider re-opening the issue.
Here is what it looks like when I try to compile the Snowflake starter project:
Similar errors show up when compiling some tutorials I had laying around (they worked under Sierra and XCode 7.3.1)

@artforlife I'm having exact same issue although not related specifically to react-native, I'm in the process of updating to xcode 8.1 as after update to macOS sierra I was unable to run tests which depend on fs, any help appreciated...
EDIT: please look at this, installing watchman fixed this issue for me
artforlife commentedon Oct 30, 2016
@bondarewicz Thanks for the idea. I have just tried downgrading to Xcode 7.3.1 and the problem still persists. This leads me to think that it lies not with Xcode but elsewhere. Perhaps the Development Tools is the problem.
My watchman version is already 4.7.0 ...
bondarewicz commentedon Oct 30, 2016
@artforlife have you tried reinstall ? We need to debug this issue as many had the same problem but there is no definite answer yet...
artforlife commentedon Oct 30, 2016
@bondarewicz I have tried reinstalling the watchman, but that didn't affect anything.
artforlife commentedon Oct 30, 2016
I have the following configurations:
OSX: Sierra
XCode: 8.1
NodeJS: 5.1.0
Watchman: 4.6.0
kern.maxfiles: 10485760
I used to following steps to fix the issue.
watchman watch-listThis fixed it. To summarize, it seems to have been a permissions problem on a Watchman directory.

Can confirm that this issue was related to tmux. After getting the error
from running react-native commands, I installed watchman, but continued to get the issue. Running react-native commands outside of tmux now works. I do not have jest installed. None of the other fixes mentioned here had any effect.

Solved for me with updating Xcode and installing watchman with brew (which is not possible with 7.x Xcode)

Also

I followed most of the steps above including upgrading watchman, and increasing the max file limit, but what solved it for me was verifying permissions by running
watchman watch-listand then following the directions it provided. Thanks @OscarT and @hghinaglia!abuammar commentedon Apr 20, 2017
updating watchman solved me the issue when i updated macOS Sierra

Note that this is also what happens if you don't have Watchman installed at all.
