I tried to follow the instructions and it failed, as julia stuff always tend to fail (with unhelpful error messages).

    (ConstraintSolver) pkg> develop .
    [ Info: Assigning UUID 761e04fa-38db-5968-92db-bac8a6ce9725 to user_name

You probably want to develop on the Constraint solver instead of just installing, right? Then you can use `] dev https://github.com/Wikunia/ConstraintSolver.jl` You currently try to develop a package which already exists and that doesn't work. Yes the error message is unhelpful.

looks like you used `activate .` to get into `ConstraintSolver Pkg>` then it's already done and you don't need develop or dev anymore Hope it helps

I just copy and pasted the first terminal commands from the post on the julia REPL and on windows it errors at line `] develop .`.

On linux, it works.

Ah I see. Can't test it on Windows just assumed it should be the same and it probably should. Glad it works now for you in linux
