Hello
I currently use iapws ( international association for properties water & steam ) which is a thermal science application ; it's a python application directly available on Debian distro but not on arch bases distros
I tried to install it through github by makepkg process , but nowhere the file PKGBUILD is included ; then I tried to make it based on a file used for yay install ; anyway , now I have still an error " no rules for pkgbuild ...."
Then my questions :
- what about an installation of an app when not in arch bases nor aur database ?
- is there a possibility to install a .deb in arch ? and how ?
note: iapws github give process to install on debian only .
iapws url :https://github.com/jjgomera/iapws

is there a possibility to install a .deb in arch ? and how ?
That can break the system as far as I understand. Arch manages packages only with pacman; using apt or dpkg is not recommended, unlike using pacman + AUR Helper or pacman + flatpak.
what about an installation of an app when not in arch bases nor aur database ?
You can create your own PKGBUILD. Since you say it is a Python package, you can follow these steps: https://wiki.archlinux.org/title/Python … guidelines
You can use the .deb package as a source, but I recommend using the source code for a Python package built from scratch: https://pypi.org/project/iapws/#files There you can see the versions and choose the most recent one.

}Note test will fail as the latest release is not compatible with scipy 1.17.0/numpy 2.4.2 due to removal of numpy aliases from scipy and stricter scalar conversion in numpy. To get test to pass I used the following patch:

Ideally upstream should update iaws to support newer scipy/numpy.

Since I didn't see the tag on GitHub, I only looked at the releases that had the outdated version, in which case the sha256sum would also change.
