Hey @Froosty we’ve been digging into this a little bit recently - apparently Nuxt.js is incompatible with pnpm < 3.x, we think because of https://github.com/pnpm/pnpm/issues/1601. Unfortunately pnpm 3 is incompatible with pnpm 2.x, which is what Glitch uses, and the migration path from 2 -> 3 isn’t a simple one for us. We’d like to make the jump, but I don’t have a timeline for when we might get to it.
npm will work fine, but that means that your packages consume project space, so Nuxt.js projects on Glitch must be fairly small.
