I pick a platform/language that's stable. e.g. Common Lisp.

The libraries everyone use typically don't change -- you can usually get away with not even specifying a version number.

The language hasn't changed since being standardized decades ago. That doesn't mean its deficient -- it's a programmable programming language, thus various things that are features of other languages are just more libraries in Common Lisp.

Sounds like you avoid the problem entirely, wish we could do the same but we've committed to a working in a ecosystem that is still quite nascent which leads to a lot of churn in our deps.
