Expected behaviour

Rails console should be loaded for rails c

Actual behaviour

Rails console doesnt load on rails c.

System configuration

Rails version: 4.2.0
Ruby version: 2.2.4p230 (2015-12-16 revision 53155) [x86_64-darwin15]

This is not an issue related to Rails. See how to solve issues with rvm and readline. You will face this issue with any other gem which tries to use readline as well as the issue with your Ruby installation.

Thanks!

@prasadsurase, I am also facing this issue now. Although it is not a Rails issue, can you please shed some light on this problem? Googled around and SO solution did not work out. Thanks

[prasadsurase]

@jeffrey008 I imploded the RVM and reinstalled it.

[LegaKh]

works for me:
ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib

16/01/2019 @saxxi upd:
ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

[enderahmetyurt]

Add 'rb-readline' gem to your Gemfile in development group and install it. It's the easiest solution for silly "readline" errors. Other solutions didn't work for me. :(

@LegaKh why libreadline.6.dylib not libreadline.7.dylib

[bparanj]

Thanks @enderahmetyurt. It works!

[jusopi]

I had to use @enderahmetyurt's solution first and then create the symlink using @LegaKh's suggestion.

[jackalcooper]

@LegaKh 's solution works for me

[keesbriggs]

@LegaKh 's solution works for me too

[victorhazbun]

@LegaKh 's solution works for me too

[alobban]

Thanks @enderahmetyurt. It definitely was the easiest solution!
Mac OSX 10.12.3, Ruby-2.3.0 and Rails-5.0.1

I was installing other framework & it caused the same error.

Thanks @enderahmetyurt. It works now!

@enderahmetyurt it is a great solution for rails c but irb requires different one.
