Can't install it on macos

I installed ArrayFire on macos using the pkg. And it seems to work because the files are at /opt/arrayfire
Now my problem is "linking" it to nodejs.
When i run : `npm config set cmake_af_path "/opt/arrayfire/lib"`

I get an error:
```
npm ERR! `cmake_af_path` is not a valid npm option
npm ERR! A complete log of this run can be found in: /Users/x/.npm/_logs/2024-01-15T14_17_49_992Z-debug-0.log
```

Anyone know why i have this error ? i follow what the readme said

先從 README 中的 macOS 和 Node.js 安裝說明開始，然後檢查文件中記載的 npm 設定命令和 `/opt/arrayfire` 路徑。重現回報的 npm 錯誤，並驗證這些說明或設定是否能在 macOS 上產生可正常運作的 Node.js 安裝。
