Stuck at Starting Packager on Windows 10

[karankashyap]

Description

Stuck at Starting Packager after npm start on Windows 10. Working on Atom and WebStorm. I have Bash on Ubuntu on Windows. Installed Watchman too

Expected Behavior

Starting Packager generally starts the packager and loads the app on device via Expo.

Observed Behavior

After dependency graph is loaded, Starting Packager is stuck forever. Solutions elsewhere are for Linux and Mac as people are saying that installing watchman somehow solves this.

• react-native info

  OS: Windows 10
  Node: 8.7.0
  Yarn: 1.2.1
  npm: 4.6.1
  Watchman: 4.9.1
  Xcode: N/A
  Android Studio: Version  2.1.0.0 AI-143.2821654

Packages: (wanted => installed)

  react-native: 0.50.3 => 0.50.3

Tried (not in order)

watchman watch-del-all
watchman shutdown-server
react-native start --reset-cache
yarn start
npm cache clean
rm -rf node_modules

but nothing works, still stuck there.

Specifications:

1. Operating system: Windows 10 x64
2. Phone/emulator/simulator & version: Samsung SMN9005 (Note 3 LTE)
3. Storage: SSD 512 GB

Possible Solution on Linux:
sudo sysctl -w fs.inotify.max_user_watches=10000
what is the windows equivalent of this?

[aalkz]

I'm having this issue as well, running watchman.exe watch-dell-all returns this output:

{
    "version": "4.9.1",
    "roots": []
}

And running watchman.exe shutdown-server returns:

{
    "version": "4.9.1",
    "shutdown-server": true
}

I don't understand how the solution for Linux works to try it on Windows, I have seen that it has worked for most people on other issue threads:

• Unable to start react-native package manager facebook/react-native#10188
• react-native-scripts start stuck at "Starting packager..." #343 (comment)
• npm start hangs on - "Starting packager..." #439 (comment)

[brentvatne]

this is an upstream react-native issue as @aalkz has pointed out.

@karankashyap, I know this is closed, but I had a similar problem and created a PR to fix, maybe it can be useful in this case. #674
