A Bundler plugin that copies compiled native extensions (.so/.bundle/.dll) into a gem's lib/ directory after installation. This is useful for old or unmaintained gems that expect their compiled extensions to live in lib/ rather than in Bundler's extension directory.
gem install bundler-extension_in_lib
Add the following to your Gemfile:
plugin "bundler-extension_in_lib"
if Bundler::Plugin.installed?("bundler-extension_in_lib")
Bundler::Plugin.send(:load_plugin, "bundler-extension_in_lib")
elsif respond_to?(:gem)
raise "Run `bundle install` first to install the bundler-extension_in_lib plugin"
end
source "https://rubygems.org"
gem "sassc", install_extension_in_lib: trueThe install_extension_in_lib: true option on a gem declaration tells the plugin to copy that gem's compiled extensions into its lib/ directory after installation.
You must run bundle install before any other Bundler command (bundle exec, bundle check, etc.). The first bundle install installs the plugin and registers it. Subsequent commands use the load_plugin call to load it before the gem declarations are evaluated. Without it, Bundler would reject install_extension_in_lib: as an unknown keyword.
Bundler doesn't eagerly load already-installed plugins before evaluating the Gemfile. The load_plugin call forces the plugin to load early, which prepends our DSL extension onto Bundler::Dsl before any gem declarations are evaluated.
This is a known limitation of the Bundler plugin system: ruby/rubygems#6961
The plugin hooks into Bundler::Plugin::Events::GEM_AFTER_INSTALL. When a gem marked with install_extension_in_lib: true is freshly installed, the plugin copies all compiled extension files from the gem's extension directory into its lib/ directory.
Files that are skipped: gem.build_complete, mkmf.log.
