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
npmfor 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 getcommand- 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
CPAN for perl was the first one and it was very successful so got copied.
Because it is way easier to manage them this way rather than have every distro package repo also support them. Additionally, windows and Mac are also targets and they don’t have built in package managers.
It is not as popular but https://conan.io/ exists. Personally, I miss working in c++ because the lack of a built in package manager made people manage dependencies more thoughtfully. It was not without tradeoffs but I preferred that world to adding a dependency being one command away.
