Error watchman took too long to load

[Palgrover]

EDIT:

Please make sure you're running watchman 3.1. You can upgrade using the following:

watchman shutdown-server
brew update
brew upgrade watchman

Then run watchman version to make sure you're running v3.1

Can you verify you installed watchman?

[Palgrover]

Yes i did the brew install

[amasad]

Can you increase the wait time in here and try again? https://github.com/facebook/react-native/blob/master/packager/react-packager/src/FileWatcher/index.js#L31

You can find this file in your project_dir/node_modules/react-native/packager/react-packager/src/FileWatcher/index.js

Same issue with me.

$ watchman
{
"error": "invalid command (expected an array with some elements!)",
"cli_validated": true,
"version": "3.0.0"
}

[amasad]

@nuno can you try bumping the wait time? and see if that works (see my previous comment)

[Palgrover]

@amasad i increased the time so the thing that changed was this error came when project was starting in simulator but now it starts fine without error but after that when i change in my index.js and reload the simulator by cmd+R it gives the same error

@amasad no not really, doubled it to 6000 and then 30000 but it still times out

[nuno]

var MAX_WAIT_TIME = 30000;

Would be great to see what's in your watchman logs.
https://facebook.github.io/watchman/docs/troubleshooting.html#where-are-the-logs
tells you where to find them; can you put them up in a gist?

[kangguru]

please see https://gist.github.com/kangguru/cdebd0615e883b324a03

but since i clear out the log file no new one was generated

[wez]

That log shows:

launchd checkin failed Operation not permitted

which is something I've not seen before. It also shows that no watches were ever established.

Can you attach the output of these commands:

uname -a
watchman watch-list
cat ~/Library/LaunchAgents/com.github.facebook.watchman.plist
/bin/ps -Awwx | grep watchman

[clauderic]

I had the same issue. Tried running watchman shutdown-server (to no avail). Restarting my computer fixed the problem for me.
