Ruby environment - what to use?

Question

ruby

You need to deploy Redmine. At first I did everything through apt-get. Then I realized that this was not the case and began to look for how they usually create an environment for ROR apps. Began to use RVM. Like what you need. I also installed Thin through RVM. All this in the user's environment. But even this is not enough. Then I started reading about gemsets and came across bundler. Something else was found there. And I'm completely confused about what and how to use. I don't need something really cool. The articles that I saw are 3-4 years old, a bit old. I just need to isolate Ruby so that Redmine will cost happily ever after. As a result, I want to automate all this through ansible.
What do you recommend to use?

Answer 1

A common and convenient bundle is rbenv and bundler.
rbenv - for maintaining ruby ​​instances, bundler - for maintaining project dependencies.
The main feature of RVM - gemsets - does not make sense with bundler.
