Why can't I just use: import vibe.vibe; for import packages like Nim or Python? Why I still use DUB?

In python you also have pip.

It is possible to use vibe.d (any dub package) without dub but you have a few manual steps involved.

Kind regards

Python dont need pip for run script with imported module. Just need call python.

Why DMD can't make automatic this few steps involved?

I don't use dub. Just dmd -i after you set up the files in the right place.

Not all libraries support that but I only use my own libraries so it is fine.

Same as for D. You can just use dub for downloading the packages and then use DMD with the correct import paths arguments/ switches / additional arguments.
The analogy here is the setup.py where you configure your dependencies in python.

Every dub package is different. Copying files, different script hooks (e.g. before generation...), and many more.
This is not in the responsibility of a compiler, but in a package manager.

But you need to install the module beforehand. The Pyhton interpreter doesn't fetch modules and install them for you. Neither does dmd.

I highly recommend Adam's arsd library (or collection of libraries). Mostly just single files, with a few that have one or two dependencies, you just copy the file(s) into your workspace and import them. That's all.  No need for external tools to manage dependencies, no dependency hell, just drop the file into your project and go.

arsd does have a dub thingy for those who want it, but I mostly just git submodule it in my own projects or plain ole copy a couple o' files into my workspace. No fuss, no muss, no hairy NP-complete dependency graphs, the way it should be.
