Why do so many programming languages have their own package manager? (sh.itjust.works)

Lots of programming languages have their own package manager, separate from the distribution or OS package manager.

Going loosely from the TIOBE index:

Python has Pip

C# has NuGet

Javascript has npm for Node.js

Visual Basic also uses NuGet

R has a repository of packages that can be installed by running install.packages("something") in R

Rust has Cargo/Crates

Go has the go get command

Swift has its own package manager swift package

Ruby has RubyGems

Java has Maven and Gradle (not sure if they are full package managers, or build automation tools with dependency resolution)

PHP has Composer for managing libraries and dependencies

C and C++ are the only exceptions I can think of, off the top of my head; libraries are managed by, and coupled to, the operating system

I agree that this doesn't seem necessary. Personally I think Nix would be a good candidate for dependency management that works consistently between languages. I think that may be partway set up for Haskell, and I've noticed that nixpkgs has a good collection of Python dependencies. But for most cases the Nix flow currently usually involves using the language's bespoke dependency manifest to generate a Nix expression that downloads dependencies from the language's bespoke package repo.

One advantage of Nix is that you don't need all packages in one repo. Nixpkgs is mostly geared for the NixOS Linux distro. Each language ecosystem could have its own repo if that makes the most sense, with Nix being the common connective language.
