Watcher took too long to load error message about react-native HOT 7 CLOSED

Can you restart your computer and try again?
Sometimes fseventsd on OSX gets into a bad state which can be solved by restarting. If that didn't work please bump the timeout we have in react-packager FileWatcher.js, maybe we need a longer one.

Let me know if either of those work.

from react-native.

I restarted my computer and tried running npm start again, without any luck. I also changed MAX_WAIT_TIME = 30000; in the react-packager/src/FileWatcher/index.js file and didn't have any luck with that either.

When I ran npm install this is the output I got:
npm WARN package.json [email protected] punycode is also the name of a node core module.
npm WARN package.json [email protected] No repository field.
npm WARN prefer global [email protected] should be installed with -g

So I ran npm install -g. I'm not sure if that makes a difference or not.

Oh, maybe this is the same error as another issue. Did you happen to have typed

npm install npm start

by chance? If yes, can you do

rm -Rf node_modules

and do

npm install

from react-native.

Oh yes, I did type that. I did the rm -Rf node_modules and npm install, but I'm still seeing the watcher error happening. When I run the simulator, the app loads, and a red screen appears. This is what the terminal has:

Error: Watcher took too long to load.

Ok I think I fixed my problem! I had installed watchman on my computer and then upgraded my computer to Yosemite so I could get the latest version of Xcode. I uninstalled watchman and then reinstalled it. That fixed the problem. I'm guessing the version of watchman I had didn't work with Yosemite? Thanks for the help!

Awesome! @amasad I think it would be nice to add something like "try running watchman from your terminal" to the "Watcher took too long to load" error message, because it can give more details about what's wrong.

I think that would help. Thanks again!
