Issue #12186 has been reported by Tsuyoshi Sawada.

----------------------------------------
Bug #12186: /snapshot/lib/rubygems/installer.rb:233
https://bugs.ruby-lang.org/issues/12186

* Author: Tsuyoshi Sawada
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: Nightly snapshot (2016-3-13 03:01)
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
I downloaded the nightly snapshot (https://cache.ruby-lang.org/pub/ruby/snapshot.tar.gz), and did:

~~~
./configure
make
sudo make install
~~~

and got:

~~~
.../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,

~~~RUBY
question << existing
~~~

and the values seem to be:

~~~RUBY
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?
