Big Sur react native how to get watchman to run?

Question

I am trying to run a react native project but I keep getting:

Watchman: watchman --no-pretty get-sockname returned with exit code=1, signal=null, stderr= 2020-12-20T01:04:27,184: [0x118044e00] the owner of /usr/local/var/run/watchman/mattroberts-state is uid 0 and doesn't match your euid 501

I think it is a permission problem but I don't know how to fix it. Does anyone know what is wrong and how to fix it?

If I could get the uid to match the euid, it seems it should be fixed, but I don't know how.

Answer 1

this worked for me sudo chmod 0700 /usr/local/var/run/watchman/$(whoami)-state

Looks like the owner of the watchman state directory is set to root. You can fix it by running:

sudo chown -R "$(whoami)" "/usr/local/var/run/watchman/$(whoami)-state"

Answer 3

While I was unable to fix Watchman, after uninstalling it the React Native app runs. I don't think it will automatically reload, but you can still cause a reload to occur with command r in the simulator.

Since I had installed Watchman with homebrew, I uninstalled it with

brew uninstall Watchman

in the terminal
