watchman took too long to load with ReactNative

[nicopasso]

Hi,

I'm facing this error when I run 'npm start' on react-native folder.

[Error: Watcher took too long to load
Try running watchman from your terminal

ERROR: could not create packager - please shut down any existing instances that are already running.

I've just installed watchman via homebrew.
How can I fix this error?

Can you try:

brew uninstall watchman
brew install --HEAD watchman

and see if that helps?

I've got the same error.

EDIT: it works...I had to restart all. Thanks!

If you're arriving here with this issue, please don't just reboot. Help us figure out the root cause by working through the following steps:

1. Get a HEAD install of watchman. This will fix some known launchd issues:

brew uninstall watchman
brew install --HEAD watchman

1. Re-try with ReactNative
2. Collect your watchman logs and put them in a gist.
   You can find them in /usr/local/Cellar/watchman/HEAD/var/run/watchman/$USER.log
3. open /Applications/Utilities/Console.app and filter by launchd and/or watchman and report
   anything that might be relevant
4. include the output from these commands:

watchman watch-list
ls -al ~/Library/LaunchAgents
launchctl list com.github.facebook.watchman

[wez]

Can you clarify what you mean by restart all?

Hi @wez....

Been having this issue on my main account on multiple computers. However, the issue does not come up when creating a new user account. Have done a HEAD install of watchman but to no avail.

• No log files exist here:

/usr/local/Cellar/watchman/HEAD/var/run/watchman

• Console app reports:

Caller specified a plist with bad ownership/permissions: path = /Users/ryanwheeler/Library/LaunchAgents/com.github.facebook.watchman.plist, caller = launchctl.5684

Here is a gist - https://gist.github.com/kellyjandrews/394097ae8786e2a352a1

[wez]

@rywhee ah, interesting. Can you chmod 644 ~/Library/LaunchAgents/com.github.facebook.watchman.plist and then run watchman watch-list?

[wez]

@kellyjandrews what happens if you run watchman watch-list?

[kellyjandrews]

{
    "version": "3.0.0",
    "roots": []
}

In all fairness - I could have no idea what I'm doing. :)

[kellyjandrews]

Ok - I went to the folder I'm trying to use this in -

$ watchman watch ./
{
    "version": "3.0.0",
    "watch": "/Users/kellyjandrews/Apps/AwesomeProject"
}

[wez]

@kellyjandrews that actually looks like watchman is working to me. Does the react-native stuff work? Can you do:

watchman watch .
watchman watch-list

[rywhee]

@wez - watchman watch-list after chmod on the plist:

{
    "version": "3.0.0",
    "roots": []
}

[wez]

@rywhee sounds like watchman is now working for you; does the react native stuff work now?
