You can install codex without npm if you build it yourself, they have migrated to rust in June and npm is just a convenient install wrapper it seems.

Just `git clone git@github.com:openai/codex.git`, `cd codex-rs`, `cargo build --release` (If you have many cores and not much RAM, use `-j n`, where n is 1 to 4 to decrease RAM requirements)
