I downloaded the nightly snapshot (https://cache.ruby-lang.org/pub/ruby/snapshot.tar.gz), and did:
./configure make sudo make install
.../snapshot/lib/rubygems/installer.rb:233:in `check_executable_overwrite': no implicit conversion of nil into String (TypeError)
The offending line installer.rb:233 looks like this,
question << existing
and the values seem to be:
question # => "rake's executable \"rake\" conflicts with " existing # => nil
Is this a bug, or is there something wrong with my environment?
Also, I am looking forward for Ruby 2.3.1. Is there a place where the schedule for the release of teeny versions are announced? Or is it is not announced until release?
