1.1.rc: bundler may install the wrong version of a gem on MRI 1.8.7 #1486

I've been testing out bundler 1.1.rc. I'm really enjoying the improved performance. I ran into what I think is a pretty serious bug, though: when using multiple gem sources (i.e., plus a private gem repo), I'm intermittently getting gem resolutions that won't work. Here's an example:

Using bundler (1.1.rc)
Your bundle is updated! Use bundle show [gemname] to see where a bundled gem is installed.

  • bundle 1.1.rc exec rake autobuild --trace Could not find activesupport-3.0.5 in any of the sources

Some of those are private gems, but the conflict is in publicly available ones: bundler selects activesupport 3.0.7 and activerecord 3.0.5, which can't be used together.

Unfortunately this behavior is intermittent — sometimes it works fine, even within this one project. I'm going to try to track it down further, but it's a serious enough issue that it seemed like reporting it first was the best option.

when using multiple gem sources (i.e., plus a private gem repo)

I noticed that another, completely public project is also having this problem. I'm seeing it in the CI build for Aker. Some links:

In this case, the output from bundle update shows that bundler installed activesupport 3.0.5 and activerecord 3.0.5, but activemodel 3.0.7. Curiously, the lockfile shows that activemodel 3.0.5 was selected, suggesting that this isn't a problem with the resolver but with the installer.

It's actually completely reproducible on MRI 1.8.7. I've updated the title to reflect this. You can reproduce it by running Aker's CI script, assuming you have RVM installed:

  • git clone git://
  • cd aker

I'll try to come up with smaller test case.

I've rolled back Aker to use bundler 1.0.21 for now, so you can no longer just clone and go if you want to try this in Aker. New steps:

  • git clone git://
  • cd aker
  • git checkout 4ed2a8

Thanks for the bug report. We've reproduced this and it's a blocker for 1.1.
