I added a package but can’t seem to have it be recognised:

Does anyone have any ideas?

Thanks

On my machine:

```julia
(scratch) pkg> add https://github.com/Staross/JuliaCMAES.git
    Cloning git-repo `https://github.com/Staross/JuliaCMAES.git`
   Updating git-repo `https://github.com/Staross/JuliaCMAES.git`
ERROR: could not find project file in package at https://github.com/Staross/JuliaCMAES.git

```

Your repo does not have the expected [directory structure](https://julialang.github.io/Pkg.jl/v1/creating-packages/) for a package. It also lacks `Project.toml`.

You will have to create a package (e.g. PackageTemplates.jl), copy the code into it, then `add` should work.

That is not a package at all, just a repository with a single source code file. Your best chance to run it is to just `include` the file, in Julia 0.5.

Thanks. I just noticed this package seems to be discontinued, perhaps superceded by Evolutionary.jl.
