Issue
arg_scanner gem not installed via ruby gems.
When attempting to use
gem install
to get arg_scanner on first pass:Resolved by explicitly installing
debase-ruby_core_source
gem.On second attempt,
gem install
errors with the following:Again resolved by explicitly installing
native-package-installer
.I noticed that the gemspec has these gems as development dependencies (https://github.com/JetBrains/ruby-type-inference/blob/master/arg_scanner/arg_scanner.gemspec#L36-L37); however, the extconf.rb requires them (https://github.com/JetBrains/ruby-type-inference/blob/master/arg_scanner/ext/arg_scanner/extconf.rb#L5-L6).
Recommendations
Three possible options present themselves to resolve this issue:
debase-ruby_core_source
andnative-package-installer
dependencies instead of development dependenciesextconf.rb
to not require them.README.md
to detail explicit install of necessary gems.Environment
