Build failed on MacOS Similar the other issue with Mac OS

[pokersolver]

So I get to this step- $ npm run tauri build

And I get this script fail and have know clue how to fix it...I am not a software engineer or coder in any way, shape or form. So please forgive me. Also I used the tar.gz release. I was guessing this was the correct one for a Mac, though ran into the same issue with the zip file as well.

warnings when minifying css:

(!) Some chunks are larger than 500 kBs after minification. Consider:

• Using dynamic import() to code-split the application

• Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/configuration-options/#output-manualchunks

• Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.
