rails console doesn't load due to libreadline

Question

I have recently reinstalled ruby 2.1.2 like so since I wanted to install a gem (ruby-debug-ide)

sudo rvm reinstall 2.1.2 --disable-binary --with         


        

Answer 1

I was able to resolve the same problem by reinstalling Ruby. On the Homebrew side reinstalling readline (even from source) didn't help.

I'm using RVM so this sorted it for me:

rvm reinstall 2.3.1

I think Homebrew may have pulled in readline v7 recently for some other package, which I suspect could well be the culprit.

Answer 2

This solved my problem:

Replace libreadline.{version}.dylib with the version you are getting error for:

ln -s /usr/local/opt/readline/lib/libreadline.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

Answer 3

Adding gem 'rb-readline' to my Gemfile fixed this problem for me. See https://github.com/ConnorAtherton/rb-readline.

Answer 4

On OSX using homebrew, you can specify which readline version is active. e.g.

brew switch readline 6.3.8

(it's likely installed in /usr/local/Cellar/readline/ )
