This is a huge pain, mostly stemming from using the same computer for different projects, because dependencies start to conflict. Big companies (fb, google, workday) solve this with cloud-hosted dev environments. Cloud environments let me contribute to our code base as a technical founder without having to have the technical expertise of a CTO. I'd rather not go back because while I know how to code, I'd rather not spend time configuring dev environments if someone can just share theirs with me. (disclaimer: I work at https://brev.dev)
