Received the following error beginning about 11 hours ago, when I run my build this on CircleCI: ``` #!/bin/bash -eo pipefail bundle install --jobs=4 --retry=3 --path vendor/bundle Gem::GemNotFoundException: can't find gem bundler (>= 0.a) with executable bundle find_spec_for_exe at /opt/jruby/lib/ruby/stdlib/rubygems.rb:289 activate_bin_path at /opt/jruby/lib/ruby/stdlib/rubygems.rb:308
at /opt/jruby/bin/bundle:23 Exited with code 1 ``` The newer version of bundler is different from the gemfile.lock file. When I removed the gemfile.lock file and installed bundler, ran bundle install again: I got the following error: ``` bundle install --jobs=4 --retry=3 --path vendor/bundle Fetching git@github.com:wcmc-its/directory-service.git Fetching gem metadata from https://rubygems.org/............. Fetching gem metadata from https://rubygems.org/. Resolving dependencies......... Bundler could not find compatible versions for gem "bundler": In Gemfile: rails (= 4.2.11) java was resolved to 4.2.11, which depends on bundler (< 2.0, >= 1.3.0) java Current Bundler version: bundler (2.0.1) This Gemfile requires a different version of Bundler. Perhaps you need to update Bundler by running `gem install bundler`? Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails (= 4.2.11)', in any of the sources. ``` Even if I install gem install bundler -v 1.17.2 (which is the version I want to use) The version of bundler I run in the command line returns 2.0.1 The configuration was working fine until 11 hours ago with this image circleci/jruby:9.2.5-browsers The rails version I am using is 4.2.11, which seems to incompatible with bundler version 2.0.1. Eventually, I would like to update my rails version 5, however we needs this working now. How can I use bundler version 1.17.2 instead of 2.0.1? ---

We were able to fix this by updating our CircleCI config to install a specific version of Bundler before running bundle install. ``` - run: name: install dependencies command: | gem install bundler -v 1.17.2 bundle install --jobs=4 --retry=3 --path vendor/bundle ``` ---

It is likely to result from upstream image changes outside of CircleCI’s control. If you get stuck with this sort of thing, pinning your docker image to a specific sha256 hash can be a handy short-term fix. ---
