Issues install Coluna.jl oj Julia 1.1

Hi - I am having a lot of trouble installing Coluna.jl on the 1.04 version of Julia. The command I am using is:

add GitHub - atoptima/Coluna.jl: Branch-and-Price-and-Cut in Julia

Which should ostensibly work out of the box ? The error I get is:

(v1.0) pkg> add GitHub - atoptima/Coluna.jl: Branch-and-Price-and-Cut in Julia
Updating git-repo https://github.com/atoptima/Coluna.jl.git
Resolving package versions…
ERROR: Unsatisfiable requirements detected for package BlockDecomposition [6cde
614]:
BlockDecomposition [6cde8614] log:
├─BlockDecomposition [6cde8614] has no known versions!
└─restricted to versions * by Coluna [88b4ec78] - no versions left

├─possible versions are: 0.1.0 or uninstalled
└─Coluna [88b4ec78] is fixed to version 0.1.0

(v1.0) pkg>

Which primarily seems related to BlockDecomposition - which I cannot install as well.

Any help would be appreciated …

Thx

Hi @rakesh_gupta,

It looks like BlockDecomposition isn’t registered. Try

] add https://github.com/atoptima/BlockDecomposition.jl
] add https://github.com/atoptima/Coluna.jl

If it doesn’t work, you should consider opening an issue at Coluna.jl: Issues · atoptima/Coluna.jl · GitHub
