Ruby Virtualenv

Inspired by Python's virtualenv project, Ruby-Virtualenv is a utility to create sandboxed Ruby/Rubygems environments.

It is meant to address the following issues:

  • Conflicts with unspecified gem dependency versions.
  • Applications can have their own gem repositories.
  • Permissions for installing your own gems.
  • Ability to try gems out without installing into your global repository.
  • A Simple way to enable this.

Running from your own gem repositories is fairly straight-forward, but managing the necessary environment is a pain. This utility will create a new environment which may be activated by the script bin/activate in your sandbox directory.

Run the script with the following to enable your new environment:

$ source bin/activate

When you want to leave the environment:

$ deactivate

Notes

  • It creates an environment that has its own installation directory for Gems.
  • It doesn't share gems with other sandbox environments.
  • It (optionally) doesn't use the globally installed gems either.
  • It will use a local to the sandbox .gemrc file

Install

$ gem install ruby-virtualenv

Usage

Create a new virtualenv (verbose output by default):

$ ruby-virtualenv ~/.ruby-virtualenvs/my-new-sandbox
creating new sandbox in ~/.ruby-virtualenvs/my-new-sandbox
installing activation script
installing .gemrc
installing gems:
  nothing to do

Create a new sandbox with specific gems:

$ ruby-virtualenv ~/.ruby-virtualenvs/my-new-sandbox -g rake,rails
creating new sandbox in ~/.ruby-virtualenvs/my-new-sandbox
installing activation script
installing .gemrc
installing gems:
  gem: rake
  gem: rails
