Packager fails on macOS 10.12 Sierra

[goldenice]

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

# check open file limit
sysctl kern.maxfiles

# edit sysctl
sudo vim /etc/sysctl.conf

# add these two lines
kern.maxfiles=10485760
kern.maxfilesperproc=1048576

# reboot
sudo reboot

# check new file limit
sysctl kern.maxfiles

2. upgrade to watchman 4.6

# clone repo
git clone https://github.com/facebook/watchman.git

# change to master branch
git checkout -b v4.6.0 v4.6.0

# run compiler
./autogen.sh
./configure --enable-lenient --without-pcre --with-python
make
sudo make install

# check watchman version
watchman -v

# result should be 4.6.0

@mc-lean you're the best!!!

@mc-lean Nice! :)

Are there any plans to update watchman in the RN-repo so RN works out-of-the-box again?

[mc13an]

@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

[aahlad-allari]

@mc-lean Thanks 👍

[kjpolaszek]

Great, it works. 👍

[zhaomiing]

thanks, you made my day :)

System doesn't report the updated value when i run sysctl kern.maxfiles (reports 300k) but upgraded to watchman 4.7.0 with brew install watchman and it seems to work

[monder]

@jalmaas value updates only after reboot. Worked for me on GM.

But indeed, just updating to watchman 4.6.0+ seems to be enough.

[jalmaas]

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:

$ node --version
v6.5.0
$ watchman --version
4.6.0
$ sysctl kern.maxfiles
kern.maxfiles: 16384
$ sysctl kern.maxfilesperproc
kern.maxfilesperproc: 10240

unfortunately it does not work for me

macOS 10.12 (16A319)

$ node --version
-> v6.5.0
$ watchman --version
-> 4.6.0
$ sysctl kern.maxfiles
-> 10485760
$ sysctl kern.maxfilesperproc
-> 1048576

React packager ready.
