Error in Pkg EEG

I tries to use the package EGG, but, when I run the command: Pkg.add(“EEG”)
(@v1.5) pkg> Pkg.checkout(“EEG”)
ERROR: Could not determine command

julia> Pkg.checkout(“EEG”)
ERROR: UndefVarError: checkout not defined

What should I do to install this package ? (autism spectrum disorder)

Thanks a lot !

I read this topic, but did not find anything useful

Fair enough, in that case your next best bet is to read the package manager documentation:

https://pkgdocs.julialang.org/v1/managing-packages/#Adding-packages

Specifically around adding unregistered packages (EEG is not available in the general registry). Pkg.checkout I believe has been removed since pre-1.0 days, so the readme of EEG is probably quite outdated. Also, don’t use the Pkg.xxx API when interacting with the package manager from within the package REPL, these are two separate ways of using Pkg.

Thanks for the advice. I will look for an alternative at Julia Neuro by JuliaNeuro
