It seems the search path is not right in this newer ruby-bundler version. Using the following Gemfile and running 'bundle --local' works fine.
root@rubygems-test:~/test# cat Gemfile path "/usr/share/rubygems-integration/2.7.0" do gem 'ffi' end root@rubygems-test:~/test# bundle --local 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. Using bundler 2.2.0.rc.1 Using ffi 1.12.2 from source at `/usr/share/rubygems-integration/2.7.0` Bundle complete! 1 Gemfile dependency, 2 gems now installed. Use `bundle info [gemname]` to see where a bundled gem is installed. Interestingly, I have 2 containers (one with ruby-bundler 2.2.0.rc.1 and another with version 2.1.4) and both of them have the same set of directories in GEM PATHS, so both should be looking at the same directories. root@rubygems-test-old:~/test# bundler version Bundler version 2.1.4 (2020-01-05 commit 32a4159325) root@rubygems-test-old:~/test# gem env RubyGems Environment: - RUBYGEMS VERSION: 3.2.0.rc.1 - RUBY VERSION: 2.7.2 (2020-10-01 patchlevel 137) [x86_64-linux-gnu] - INSTALLATION DIRECTORY: /var/lib/gems/2.7.0 - USER INSTALLATION DIRECTORY: /root/.local/share/gem/ruby/2.7.0 - RUBY EXECUTABLE: /usr/bin/ruby2.7 - GIT EXECUTABLE: - EXECUTABLE DIRECTORY: /usr/local/bin - SPEC CACHE DIRECTORY: /root/.local/share/gem/specs - SYSTEM CONFIGURATION DIRECTORY: /etc - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /var/lib/gems/2.7.0 - /root/.local/share/gem/ruby/2.7.0 - /usr/local/lib/ruby/gems/2.7.0 - /usr/lib/ruby/gems/2.7.0 - /usr/lib/x86_64-linux-gnu/ruby/gems/2.7.0 - /usr/share/rubygems-integration/2.7.0 - /usr/share/rubygems-integration/all - /usr/lib/x86_64-linux-gnu/rubygems-integration/2.7.0 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :backtrace => false - :bulk_threshold => 1000 - REMOTE SOURCES: - https://rubygems.org/ - SHELL PATH: - /usr/local/sbin - /usr/local/bin - /usr/sbin - /usr/bin - /sbin - /bin root@rubygems-test:~/test# bundler version Bundler version 2.2.0.rc.1 (2020-10-24 commit unknown) root@rubygems-test:~/test# gem env RubyGems Environment: - RUBYGEMS VERSION: 3.2.0.rc.1 - RUBY VERSION: 2.7.2 (2020-10-01 patchlevel 137) [x86_64-linux-gnu] - INSTALLATION DIRECTORY: /var/lib/gems/2.7.0 - USER INSTALLATION DIRECTORY: /root/.local/share/gem/ruby/2.7.0 - RUBY EXECUTABLE: /usr/bin/ruby2.7 - GIT EXECUTABLE: - EXECUTABLE DIRECTORY: /usr/local/bin - SPEC CACHE DIRECTORY: /root/.local/share/gem/specs - SYSTEM CONFIGURATION DIRECTORY: /etc - RUBYGEMS PLATFORMS: - ruby - x86_64-linux - GEM PATHS: - /var/lib/gems/2.7.0 - /root/.local/share/gem/ruby/2.7.0 - /usr/local/lib/ruby/gems/2.7.0 - /usr/lib/ruby/gems/2.7.0 - /usr/lib/x86_64-linux-gnu/ruby/gems/2.7.0 - /usr/share/rubygems-integration/2.7.0 - /usr/share/rubygems-integration/all - /usr/lib/x86_64-linux-gnu/rubygems-integration/2.7.0 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :backtrace => false - :bulk_threshold => 1000 - REMOTE SOURCES: - https://rubygems.org/ - SHELL PATH: - /usr/local/sbin - /usr/local/bin - /usr/sbin - /usr/bin - /sbin - /bin I'll keep investigating to understand what is going on. -- Lucas Kanashiro
