Since I know almost nothing about Ruby, I'll ask the fedi hivemind for tips...
If I want to start up a Ruby REPL and import 'net/http' so that I can try one request using the latest version of the Gem, what steps should I follow? In Python I'd create a virtualenv and then use 'pip install' to install the package I want - so I assume something similar exists for Ruby. Bonus points if I can do the same thing but intentionally use an older (specific) version of the Gem.
@kevin well if you just want to try it and you have a system ruby, then it's "irb". then require "net/http".
if you want the equivelent of a venv, install rbenv.
@kevin For managing Ruby versions, either rbenv or the newer rv are fine choices.
With the desired Ruby version installed and active (verify with `ruby -v`), start an interactive Ruby shell with the `irb` command.
Once in an IRB session, `require “net/http”` and the Net::HTTP module should be available.
Do note that Net::HTTP is a bit of a pain to work with. There are a bunch of alternatives, though. I tend to reach for the http gem, but Faraday is also quite popular.
@kevin Bundler has an inline mode that is great for single scripts (and the REPL, I assume, although I'm not sure I've ever used it like that).
