Fails to install dependencies with no detailed error logging

[iamnafets]

I installed dev3000 and tried to run in a yarn workspace monorepo (uses turbo, fwiw) directly inside an individual nextjt package.

➜  web git:(main) ✗ dev3000

Yeah, I've encountered this to - forgot to pnpm i and it just hangs

[alistairholt]

The same here after using pnpm install -g dev3000. I had to cd into the installation directory and run pnpm install before it would work.

I realised I’m an idiot and that it's meant to replace your dev command after looking at https://dev3000.ai/ 🤦‍♂️

[elsigh]

yeah, that's to-be-expected since it really just runs pnpm dev under the hood. Will add better graceful exit

New version published to github (v0.0.55) should address this by bailing and encouraging you to pnpm install and then try again
