Installing aiida-hubbard downgrades aiida-core even when a newer version is already installed

[NarjesJOMAA]

When installing "aiida-hubbard" via "pip install aiida-hubbard", it downgraded my existing "aiida-core==2.6.3" to "2.5.2", even though 2.6.3 was already installed.
Even if "aiida-hubbard" is only compatible with "<2.6", it would be better if this was made more explicit to avoid unintended downgrades when a newer version is already installed.
Thanks!

Hello, thanks a lot for the interest in our code!

Indeed, it is not compatible. It is currently highlighted in the compatibility matrix of the README on the main page: https://github.com/aiidateam/aiida-hubbard?tab=readme-ov-file#compatibility-matrix

Do you have any suggestion where to make this more explicit? Where would you like to find this information further?

As a side note: while aiida-core v2.6 has some more functionalities, the downgrade has no dramatic effects on the installation (e.g. on your database, etc).

Hello,

It might be helpful if a warning message were shown when running « pip install aiida-hubbard » to let users know that some important dependencies like "aiida-core", "aiida-quantumespresso", etc. might be modified.

Thanks for your work and support !

Hi, unfortunately there is nothing we can do on our side for the pip install command, as far as I know.

Thanks for the info!
I’m starting to explore AiiDA and working on my own plugin.
Is there a way to make the installation fail completely if an incompatible version is already installed?

I honestly don't know. Maybe there is an option for pip install? You could have a look on the pip documentation.

Btw: aiida-core v2.7.0 will be again compatible with aiida-hubbard. The incompatibility with v2.6 is due to how the files are handled when copied from a calculation folder to an other one. If you are developing your own plugin this could be helfpul to keep in mind.
