react-native run-android error on windows: Watchman was not found in PATH

Question

I install react-native on windows 7 x64 using the official site guide.

When i test the instalation using react-native run-android inside my project folder, i got the following error on React Packager:

React Packager Watchman Error

I already tried:

• Downloaded Watchman Alpha from https://github.com/facebook/watchman/issues/19, extract .zip and set manually watchman.exe in the path on environment variables.

The error still appearing.

Anyone knows how to fix this?

Answer 1

Had similar issues on windows. run npm -g uninstall watchman. react-native was able to run smoothly. Turns out its a file watching service with quirks on windows, you could use other file watching service. I'd also recommend using genymotion for your emulator, save yourself the headache.

Answer 2

Just do an
npm -g uninstall watchman
npm -g install watchman
and hopefully that will fix your issue.
