Answer 1

I was experiencing a similar problem but with more updated versions. The error I had was:

dlopen(/Users/juanjo/.rvm/rubies/ruby-2.5.3/lib/ruby/2.5.0/x86_64-darwin18/readline.bundle, 9): Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib (LoadError)
  Referenced from: /Users/juanjo/.rvm/rubies/ruby-2.5.3/lib/ruby/2.5.0/x86_64-darwin18/readline.bundle
  Reason: image not found - /Users/juanjo/.rvm/rubies/ruby-2.5.3/lib/ruby/2.5.0/x86_64-darwin18/readline.bundle

The important part is Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib

Looking at /usr/local/opt/readline/lib/ I saw I had installed libreadline.8.dylib, not 7.

To solve my problem, guided by the other answers, I had to do the following:

ln -s /usr/local/opt/readline/lib/libreadline.8.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

In other words: ln -s /.../[libreadline you have] /.../[libreadline you need].
