About:
Rbenv is a lightweight, unobtrusive version manager for Ruby. It lets you switch between multiple Ruby versions on a per-project basis, simplifying dependency management. Unlike heavier alternatives, it hooks into your shell and requires no shell reinitialization.
Key Features:
  • Seamless version switching via shell integration
  • Per-project Ruby versions via .ruby-version files
  • Plugin extensible architecture
  • Minimal overhead and no executable wrappers
  • Simple and predictable behavior
Use Cases:
  • Managing Ruby versions across different software projects
  • Isolating project dependencies to avoid version conflicts
  • Automating CI/CD pipelines with specific Ruby versions
Alternatives:
  • RVM – RVM is a more feature-rich tool that manages gemsets and system-wide Rubies, whereas rbenv is lighter and focuses solely on version switching.
  • asdf – asdf is a multi-language version manager that uses rbenv-style shims, offering broader language support but with slightly more complexity.
