Another way to make packages available offline is to [create a custom sysimage](https://julialang.github.io/PackageCompiler.jl/dev/sysimages.html#Creating-a-sysimage-using-PackageCompiler) with [PackageCompiler.jl](https://github.com/JuliaLang/PackageCompiler.jl):

> Julia’s package manager relies on internet access, so it can be challenging to make dependencies available on secure systems. [PackageCompiler.jl](https://github.com/JuliaLang/PackageCompiler.jl) compiles Julia code ahead of time, primarily for [improved performance in certain workflows](https://julialang.github.io/PackageCompiler.jl/dev/index.html#PackageCompiler). In particular, [generating a sysimage](https://julialang.github.io/PackageCompiler.jl/dev/sysimages.html) produces a performant stand-alone Julia session, and since its [main drawback (version locking)](https://julialang.github.io/PackageCompiler.jl/dev/sysimages.html#Drawbacks-to-custom-sysimages) is mitigated on secure systems, it seems to be the best approach for putting a Julia session on a system without internet access or…
