Hello,

I tried installing the ReinforcementLearning.jl package in my environment and I get the following error:

```julia

```

Can someone explain what I should do to resolve the compatibility issue? I do not understand where the compatibility issue lies. I tried removing different packages but this does not work. I can load in the package in my script, but it doesn’t appear in my environment. I can also run the one-dimensional walk tutorial without a problem. This is strange as I do not see it in my environment, yet I can run the package either way.

Many thanks in advance for your help.

kr,

Korilium

If you need any other information, I will gladly provide it.

One option to debug this: First, create an empty project:

```julia
mkdir test
cd test
julia --project="."

```

Then, in Julia:

```julia
using Pkg
Pkg.add("ReinforcementLearning")

```

If that succeeds, add step by step the other packages you need.

If you are lucky, all works well, if not you know which package is lacking compatibility with ReinforcementLearning.
