The key part of the error message was:
Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib (LoadError)
Referenced from: /Users/stokern/.rbenv/versions/2.5.3/lib/ruby/2.5.0/x86_64-darwin17/readline.bundle
Reason: image not found - /Users/stokern/.rbenv/versions/2.5.3/lib/ruby/2.5.0/x86_64-darwin17/readline.bundle
The fix was to add the ruby readline gem:
group :development, :test do
...
gem 'rb-readline'
end
This is the second time this has caught me out, so I thought I'd document it.
You're welcome
