The most downside of Python is this. Setting up the environment and dependency management is very confusing and hard to start in the first place. Especially for Python there are a lot of non-programmer users. It seems to be easier to do right in the first place than fix everything. JavaScript yarn is really good but only based on npm already done most things okayish. A good news is that modern languages like Go, Rust, Elixir, etc designed more carefully with this, providing much better experiences.
