You might want to pick up a course on using google, cause the first hit on "julia package manager" is the documentation: https://docs.julialang.org/en/v1/stdlib/Pkg/ https://docs.julialang.org/en/v1/stdlib/Pkg/ "WTF does `activate .` even do?" If you then read it, it says "If you are ever stuck, you can ask Pkg for help:". (@v1.6) pkg> ?activate activate activate [--shared|--temp] [path] Activate the environment at the given path, or the home project environment if no path is specified. The active environment is the environment that is modified by executing package commands. [...] Also the docs tell you in a highlighted blue bubble that if you don't want to use the "REPL-centric workflow" there is also the API: > This guide relies on the Pkg REPL to execute Pkg commands. For non-interactive use, we recommend the Pkg API. The Pkg API is fully documented in the API Reference section of the Pkg documentation.
