asdf: Extendable version manager ⇝

If your work involves multiple languages and multiple tools for managing versions, check out asdf, an extendable version manager that provides a single consistent interface for managing them all:

# List all installed ruby versions
❯ asdf list ruby
1.9.3-p545
2.1.2
2.2.3
2.2.4
2.2.5
jruby-9.1.6.0

# Install a new ruby version
❯ asdf install ruby 2.3.3

# List available nodejs versions to install
❯ asdf list-all nodejs

# Install a new nodejs version
❯ asdf install nodejs 7.7.2

I've been using asdf as my primary version manager for Ruby and Node for a few weeks and am really liking it.
