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

It's not that it's a bad idea, it's more that it's basically impossible at this point.

Bazel can't use Cargo, CMake and so on for downloading & building packages because it is trying to do cross-language builds the right way - a single build graph that includes everything. No other third party package managers/build tools actually exposed their build graphs - only commands to perform builds, which are too coarse for Bazel.

To put it simply, its necessary if you are doing things at the scale of Bazel.
