Hi, I'm new and have issues with installation.
I wanted to use ELAN on Visual Studio Code. In one of the installation steps, it is mentioned to use the command "elan toolchain install leanprover/lean4:stable", which starts downloading the file "lean-4.20.0-windows.tar.zst". However, due to my very poor internet connection, this download fails every time. I have directly downloaded the "lean-4.20.0-windows.tar.zst" file myself. Now, how can I use toolchain to install it from the file on my computer's hard drive (the downloaded file) instead of downloading it from the internet?

ELAN is rustup, so maybe in rust comunity people can help too

i seem to recall from multiple conversations that this is a common misconception?

or actually, that might be lake being related to cargo

Elan is derived from the rustup codebase. Lake takes some inspiration from Cargo (and other package mangers / build systems), but has no code overlap.
