Pretty good example of what I name the "Small island problem".

And the main reason why I hate language specific package manager.

Phase 1- Every language try to reimplements its own package manager because it is seen as a "must have" for any modern language.

Phase 2 - The language specific package lanager is designed as if they live on a small isolated island. They do not try to integrate with other languages nor care about system libraries like OpenBLAS.

They do not manage properly versioning, diamond dependencies or ABI for basic libraries written in C C++, Fortran, Rust,....

Phase 3- the ecosystem grows up and the entire things blow up spectacularly in production due to the previously ignored problems.

The list of reasons can be pretty long: duplicated packages, ABI issues, portability issue, lack of sandboxing, poor system integration...).

Phase 4- Someone try to fix the mess by creating one more language specific package manager and we start again Phase 1.

And the problem is never solved because it is a structural problem and not an implementation one: At scale, language specific package managers are a terrible idea.

Taking into consideration the diversity of your ecosystem is not an option: it is a necessity.

Currently, the python and the JS ecosystems are beautiful examples of how far this madness can go.
