Don’t do this.

Kinda. What is inside `~/.julia/packages` is not the same as what is installed and putting something there does not make it available to `using`. What is available to `using` is governed by the `Project.toml` file. The default one is located under `~/.julia/environments/v1.0/Project.toml` and is accompanied with `~/.julia/environments/v1.0/Manifest.toml`. You can try to copy your `~/.julia/packages` folder together with the `Project.toml` and `Manifest.toml` files to the other computer. In theory this should work for pure Julia packages. It will fail for packages with binary dependencies though, since you copy between two OS.
