Issue installing Torch on M1 Mac

[masonyoungblood]

Installation of Torch in R on an M1 Mac fails with the following error:

I've tried downloading the files manually, as per the installation docs, but the liblantern links gives me the following:

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<Error>

<Message>Access denied.</Message>
<Details>Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object. Permission 'storage.objects.get' denied on resource (or it may not exist).</Details>
</Error>

I've tried this process on a different internet connection so it's unlikely to be a firewall issue. Do you know what the problem might be?
