is anyone able to help? tried to run: curl -L -O https://static.pantsbuild.org/setup/pants && chmod +x ./pants rm -rf ~/.cache/pants/

Hi, sorry for the inconvenience. Are you setting up Pants in a new repo or an existing one that is already set up?

an existing one which has been set up already

for triage, I can install that version on my Mac monterey 12.0.1, but fails with

14:21:11 [INFO] initializing pantsd...
14:21:11 [ERROR] Could not initialize store for process cache: "Error making env for store at \"/Users/x/.cache/pants/lmdb_store/processes/f\": Too many open files"

@curved-television-6568 the

ulimit -n 4096

should resolve your issue

Since you're using an existing repo, you should use the

pants

script in that repo, not download a new one

The issue was it needed x86 python emulated

Ah, did that fix things?
