> Why do we ever install anything

To be able to reproduce all the procedures reliably, constantly, and without an internet connection. At least it's a requirement for my job and some other industries. Also because it's good to be serious about your job, and because reproducible builds is a nice thing to do.

This _does_ seem to "install" things to a DOTSLASH_CACHE dir though.[1] It seems similar to tools like nvm of pyenv but in this case can handle more than just a single target language. Pretty neat.

Well, it looks like you have to install DotSlash.
