Cannot install Fermi.jl due to version constraints

New to Julia

I am trying to install Fermi.jl on the newest stable release of Julia. On doing a fresh install and activating a completely new environment, when I do ] add Fermi, I am met with the following error message :

(@v1.11) pkg> activate .
  Activating new project at `~/swapan-lab/polariton`

(polariton) pkg> add Fermi

I am unsure how to resolve this issue, any help is highly appreciated.

It looks like Fermi hasn’t had a release in ~3 years and asusch is forcing some fairly old package versions. Does ]add Fermi#master work?

Yes it does work, thank you so much!

It does give a few warnings during precompilation though :

A new version of Fermi was just tagged, so the workaround should no longer be necessary.
