Bundler 1.17.2 fails on Ruby 1.9.2

[schneems]

Hello. I'm seeing this failure when running bundle install with Bundler 1.17.2 on Ruby 1.9.2:

NameError: undefined local variable or method `options' for #<Bundler::RubyGemsGemInstaller:0x000000082b8128>

Here's how to reproduce with docker:

$ docker pull allenwei/ruby-1.9.2
$ docker run -i -t allenwei/ruby-1.9.2:latest /bin/bash

Inside of the container:

$ ruby -v
ruby 1.9.2p330 (2014-08-07 revision 47094) [x86_64-linux]
$ git clone https://github.com/sharpstone/mri_192
$ cd mri_192/
$ gem install bundler -v 1.17.2
$ bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin -j4 --deployment

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

An error occurred while installing rack (1.5.0), and Bundler cannot continue.
Make sure that `gem install rack -v '1.5.0' --source 'https://rubygems.org/'` succeeds before bundling.
