I’d like to say that I have been using asdf to manage all of Erlang, Elixir, Ruby, Haskell, Idris, Rust, Postgres, PHP, Node.js and Crystal without any problems. The problems with installing from git master, tag or commit hash seem to be fixed, as far as I know. (I use the master version of Elixir and the nightly version of Rust, for instance).
The great advantage of asdf is that it handles all the tool-specific version management for you, and you do not have to remember all the different installation procedures for each of them.
I think @NobbZ’ advice thus is outdated now, but of course YMMV ;-).
