I think you are misunderstanding. There’s plenty of tooling for good Python env / package management, but when you need a custom compiled extension module with dependencies to maintain parity both in the database (recompiled with the custom extension packages each round trip) and outside the database, it’s a big problem. The problem is not generally making an environment, it’s that different projects need different environments but need the same database.
