Watcher took too long time to load(NodeWatcher) - React Native

Question

I am trying to run already built application in my mobile. When i start the app with "react-native start" code, it returns the following error message after some time

ERROR  Watcher took too long to load (NodeWatcher)
Error: Watcher took too long to load (NodeWatcher)
at Timeout._onTimeout (index.js:99:16)
at ontimeout (timers.js:386:14)
at tryOnTimeout (timers.js:250:5)
at Timer.listOnTimeout (timers.js:214:5)

I am using Windows 7 (32 Bit). I dont find any "Watchman" release for windows 7 32bit system. Because of this issue, i got the following error after installing my app in mobile

Reference Error: Can't find varaible: __fbBatchedBridge

Edit: now i have upgrade my system to windows8 with 64bit. But still i was not able to install the watchman.

What version of react-native and watchman are you using? I think I have your problem resolved, I just need to confirm versions. — Kyle Richardson, Jul 24 '17 at 17:10
Is the React Native project director a git repository? how you installed watchman? — Balasubramanian, Jul 26 '17 at 03:13
I have downloaded it from here. facebook.github.io/watchman/docs/install.html. It said there is no release for windows 7 32bit system, So i havent installed watchman — viji, Jul 28 '17 at 11:12

You can try to edit a file from react-native packager

node_modules\react-native\packager\react-packager\src\FileWatcher\index.js

Change the line 17 MAX_WAIT_TIME to 60000.

my node_modules\react-native\packager\react-packager\src folder doesnt have FileWatcher. Could you please tell me how to include it? – viji Jul 21 '17 at 12:34
@viji This is why I asked for the version you're using. This is likely the problem, but the solution will depend on what you are using. – Kyle Richardson Jul 24 '17 at 17:24
@KyleRichardson I have downloaded it from here. https://facebook.github.io/watchman/docs/install.html – viji Jul 28 '17 at 10:50
