brew install deno # works with no issues and much faster
Though, at the bottom of https://deno.land/#installation, one sees the incantation:
cargo install deno --locked
I removed brew's deno, installed rust (via brew) and then tried this. No compile errors. And swc_ecma_transforms compiled successfully.
