Hi,

It seems like you're encountering an issue with the primordials error, which is common when trying to run older packages (such as pac) on a newer version of Node.js. This happens because the primordials reference was removed in newer versions of Node.js, and certain libraries (like older versions of graceful-fs or pac) still depend on it.

Here’s how you can resolve this:

Solution 1: Upgrade the pac package

If possible, try upgrading the pac package to the latest version. Newer versions of pac may have fixed this issue to work with modern Node.js versions.

Check for updates:
Run the following command to check if there's an update for pac:
npm outdated pac
Update the package:
If an update is available, you can upgrade it by running:
npm install -g pac

OR
Solution 2: Downgrade Node.js to a compatible version
If you're unable to update pac, you can use a Node.js version that is compatible with your current pac version. The error is typically associated with Node.js v12 and later, so downgrading to Node.js v10 should resolve the issue.
You can use nvm to switch to Node.js v10:

Install Node.js v10 using nvm:

nvm install 10
nvm use 10

Re-run pac and check if the error still occurs.

OR
Solution 3: Apply a patch for graceful-fs
If you can't update pac or downgrade Node.js, you could manually patch the issue by upgrading the graceful-fs dependency inside the pac package:

Navigate to the pac package directory:

cd /Users/atreyarunsinainadkarni/.nvm/versions/node/v16.20.2/lib/node_modules/pac

Install a newer version of graceful-fs:

npm install graceful-fs@latest

Try running pac again.

OR
Solution 4: Use the natives package workaround
In some cases, the issue might be resolved by installing the natives package that is compatible with your Node.js version.

Install natives package:

npm install natives

Try running pac again.

Hope this helps.

Thanks!
