Issue #15469 has been updated by hsbt (Hiroshi SHIBATA). Status changed from Open to Assigned Assignee set to hsbt (Hiroshi SHIBATA) What's the version of csv library that is you expected? I wonder csv-1.0.0 on your Gemfile. ---------------------------------------- Bug #15469: Ruby2.6 included `bundler` does not handle specified `csv` gem. https://bugs.ruby-lang.org/issues/15469#change-75933 * Author: watson1978 (Shizuo Fujita) * Status: Assigned * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) * Target version: * ruby -v: * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- I want to use `csv` library which is same version of Ruby 2.5. Because Ruby 2.6's csv library has some breaking changes and they break our product. However, Ruby 2.6's `bundler` does not handle `csv` which I specified the version. ## Test code * Gemfile ``` source "https://rubygems.org" gem 'roo' gem 'csv', '1.0.0' ``` * test.rb ``` require "bundler/setup" require "csv" p CSV::VERSION ``` ## Result ``` $ bundle exec ruby -v test.rb ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin18] "3.0.2" ``` `CSV::VERSION` shows `3.0.2` and it indicates that Ruby 2.6 included `csv` library was used. ## Workaround If I install the `bundler` gem through `gem install bundler`, it works well. ``` $ gem install bundler Fetching bundler-1.17.3.gem Successfully installed bundler-1.17.3 1 gem installed $ bundle exec ruby -v test.rb ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin18] "2.4.8" ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
