Can't install a new version of Ruby using rbenv after upgrade of readline to 6.3.3

[jcapron]

Overview

I use rbenv to manage my different versions of ruby. I already had several versions installed (1.9.3 and 2.1.1) and I needed to install 2.0.0. Here is what I got:

$ rbenv install 2.0.0-p451

Cause

After some research I found this issue was mentioned here.
As explained in the thread, it turns out that the issue was from the latest upgrade of readline from 6.2.4 to 6.3.3.

Solution for now

The solution for now is to downgrade from readline 6.3.3 to 6.2.4 using this raw URL.

$ brew uninstall readline && brew install https://raw.githubusercontent.com/Homebrew/homebrew/0181c8a1633353affefabe257c170edbd6d7c008/Library/Formula/readline.rb

This is a problem in ruby that has been fixed upstream, but not released yet. Homebrew's ruby formula is using the upstream patch to work around it.

readline 6.3 was released two months ago, but we didn't update until 10 days ago, in part to give third parties time to sort out issues like this. rbenv has been aware of it since at least rbenv/ruby-build#526. It's up to them to address it.

Closing because there's not any action for Homebrew to take here.
