Try making a new environment for Yao. If you’re unfamiliar with environments, give this a read [4. Working with Environments · Pkg.jl](https://pkgdocs.julialang.org/dev/environments/)

To make an environment for Yao, paste the following in your julia REPL

```julia
activate Yao #This will create a folder named Yao in your home directory. You can change it to wherever you want with activate pahth_name/Yao. This folder contains a Project.toml
add Yao, CuYao, YaoPlots, YaoExtensions #And other packages you want to add. They'll get added to the Project.toml for this environments

```

I hope this helps
