specifier.includes is not a function

[devongermano]

I've uninstalled pnpm, and nvm on my Mac. Tried wiping every directory I could possibly think of with pnpm / node caches. Reinstalled nvm using brew, and reinstalled pnpm using corepack, But no matter what I try, whenever I run the pnpm command. I get:

pnpm: specifier.includes is not a function

Does anyone have any idea what this means? At this point, I'm at a complete loss, other than completely wiping my Mac and trying with a fresh install.
