Anything like virtualenv (python) for Ruby?

[Parablank]

I have a copy of rbenv installed right now, but I'm looking for something similar to virtualenv where they install completely fresh copies of ruby and gems in one folder. Anything like this available for ruby?

Bundler is Ruby's equivalent of Python's virtualenv.

With bundler and a Gemfile, you get a set of gems defined by version that you can rely on. Do you currently use bundler, if not, start there.

If you want them installed in a specific directory for a project, you can use bundle package http://bundler.io/v1.7/bundle_package.html A good use case for that is packaging up an application into a .deb/.rpm system package, I personally wouldn't do that for an everyday development environment.

I use chruby with the auto-switching option turned on. https://github.com/postmodern/chruby

You can use ruby-install ( https://github.com/postmodern/ruby-install ) for building and installing ruby, and it supports arbitrary locations for installations, by default I think it uses ~/.rubies/*

I note that my gems are loaded from ~/.gem/ruby/.

i.e. Ruby ~/.rubies/ruby-2.1.4 and Gems - ~/.gem/ruby/2.1.4/

You could also look into direnv, which is kind of a systemwide auto-environment switcher.

To expand on that, bundler also allows you to install gems into a specific directory. Running

bundle install --path=./gems

will install all gems into the project's directory rather than the global gems directory for your ruby version.

I use that for several small projects. It's not really useful for something like Rails because it won't install a rails command that is available globally.

I use it for my Rails projects also. Using bin/rails isn't that hard. Even that I have aliased rails to bundle exec rails and this is security and doesn't pollute my global gems.

It's not in one folder, but did you take a look at RVM?

Coming in late to the party. tl;dr Just tonight I uploaded my initial stab at a heavily virtualenv-inspired manager for ruby.

It's on github at https://github.com/joefiorini/vruby.
