Error in Ruby 2.6 when trying to shell out to invoke `irb` while in a `bundle exec` session
Third Party's Issue
ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin17]
Hello. This script fails on Ruby 2.6 but works successfully with Ruby 2.5:
cd /tmp mkdir irb-issue cd irb-issue chruby 2.6 echo 'source "https://rubygems.org"' > Gemfile bundle install bundle exec ruby -e 'puts `echo "1 + 1" | irb --simple-prompt`'
Here is the failure:
$ bundle exec ruby -e 'puts `echo "1 + 1" | irb --simple-prompt`' Traceback (most recent call last): 2: from /Users/rschneeman/.gem/ruby/2.6.0/bin/irb:23:in `<main>' 1: from /Users/rschneeman/.rubies/ruby-2.6.0/lib/ruby/2.6.0/bundler/rubygems_integration.rb:482:in `block in replace_bin_path' /Users/rschneeman/.rubies/ruby-2.6.0/lib/ruby/2.6.0/bundler/rubygems_integration.rb:462:in `block in replace_bin_path': can't find executable irb for gem irb. irb is not currently included in the bundle, perhaps you meant to add it to your Gemfile?
