React-native: Watchman was not found

[junaidahmed93]

Hello everyone,
I am new to react-native. I have already installed watchman using npm but still facing this problem.
Also tried some manual installation process for watchman but no luck.

  Usually this happens when watchman isn't running. Create an empty `.watchmanconfig` file in your project's root folder or initialize a git or hg repository in your project.

the message is fairly clear: Error: Watchman was not found in PATH. try to google for it, I'm sure you'll find something

[ericvicenti]

Yes this should be fixable with a proper installation of watchman and putting it in your PATH env. Feel free to re-open if this isn't the issue and you have more details

What does it mean by proper installation of watchman
it seem there is nothing to install watchman for windows.
I haven't found a single way to install watchman on windows, already tried with, scoop , chocolatey but there is nothing to install. Only npm providing watchman package but the error is same again after re-installations
.

I have the same issue here...

Likewise, I ran npm install -g watchman but still no dice.

[junaidahmed93]

try npm uninstall -g watchman then build (without installing again).

[davkuzmin]

That fixed it!

[aniket-jft]

try npm uninstall -g watchman then run npm install -g watchman

On mac, try to uninstall watchman and install with homebrew.
npm uninstall -g watchman
brew update
brew install watchman
