Code change never showing up on reload (Hot reload not working either)

Description

So I am following the sample app. This used to work on my old machine, but I moved to a new one and suddenly it’s not working.

Seems like watchman is not detecting file changes anymore?

AwesomeProject ➜ npm run start

> AwesomeProject@0.0.1 start /Users/jordan/Desktop/AwesomeProject
> node node_modules/react-native/local-cli/cli.js start

I see the above when I run npm run start. If I make a change to index.ios.js and save it, nothing happens. And if I hit CMD-r the simulator reloads but my change does not appear unless I stop npm run start and run it again.

Reproduction

I just did this:

react-native init AwesomeProject
cd AwesomeProject
react-native run-ios

And then ran npm run start or even if I do react-native run-ios, same issue.

Additional Information

react-native-cli: 1.2.0 react-native: 0.37.0 node: v7.0.0 watchman: 4.7.0

Hey everyone. @leeight @RomualdPercereau @chanceeakin @bluefantasy728 Did some playing around and wasn’t getting answers anywhere.

I did the following and it seems to be working now:

rm -rf /usr/local/var/run/watchman && brew uninstall watchman && brew install watchman

Hopefully that works for you!

@Jonovono: It worked!!!
