Ruby equivalent of virtualenv?

Solution 1:

RVM works closer to how virtualenv works since it lets you sandbox different ruby versions and their gems, etc.

Solution 2:

Neither sandbox, RVM, nor rbenv manage the versions of your app's gem dependencies. The tool for that is bundler.

• use a Gemfile as your application's dependency declaration
• use bundle install to install explicit versions of these dependencies into an isolated location
• use bundle exec to run your application

Solution 3:

I'll mention the way I do this with Bundler (which I use with RVM - RVM to manage the rubies and a default set of global gems, Bundler to handle project specific gems)

bundler install --binstubs --path vendor

Running this command in the root of a project will install the gems listed from your Gemfile, put the libs in ./vendor, and any executables in ./bin and all requires (if you use bundle console or the Bundler requires) will reference these exes and libs.

Solution 4:

No one seems to have mentioned rbenv.
