Same issue, on:

OS: Windows 10 10.0.19044
Node: 16.14.2 - C:\Program Files\nodejs\node.EXE
npm: 8.5.0 - C:\Program Files\nodejs\npm.CMD
react: 17.0.2 => 17.0.2
react-native: 0.67.3 => 0.67.3

watchman installed with choco

Additionally, flipper debugger could not detect watchman executable even though I installed it.

Solution

After some digging, I noticed this may be an issue with watchman newer versions. So for me the solution was:

1. choco uninstall watchman
2. choco install watchman --version 2021.01.11.00 -y (or any version you want as long as it works)

After that, the error message disappeared & flipper detected watchman successfully.
