rails c not working in rails 5

Question

On using the command in terminal inside a rails 5 application

rails c

the error thrown is given bellow. I have no idea what this means in a similar question here that for which the solution was to use spring stop. I have tried that too but no it still gave the same error. it would be great if somebody can point out the mistake here.

Have you updated HomeBrew? and / Or Have you updates to Mac OSX Sierra? This error is most likely caused from updating homebrew as it has been patched for Sierra — Shawn Wilson, Nov 05 '16 at 07:29
Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib is the issue — Shawn Wilson, Nov 05 '16 at 07:30

I recently had this problem when I updated HomeBrew, I'm also working with rails 5 and found this solution and it worked for me:

ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib

Source: https://gist.github.com/mcshakes/c87e8adda174c73be354094800b9756d

UPDATE

For readline 8 and newer versions, follow the answer given by @Cody Elhard

Works! Ruby 2.5.0, Rails 5.1.4 os/x – Terry Ray Jan 23 '18 at 20:56

Or it could be: `ln -s /usr/local/opt/readline/lib/libreadline.8.dylib /usr/local/opt/readline/lib/libreadline.7.dylib` – 0bserver07 Jan 15 '19 at 22:01

If you have readline 8 you will need to do `ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib` – nzajt Feb 12 '19 at 22:18
Can this be considered a fix? Fixing a pointer to non-existent file by mimicking that file hardly seems like a solution. Rather a quick patch. Is there a way to make it point to the correct file? – Kkulikovskis Mar 06 '19 at 13:33

As a general approach if this error occurred due to updating readline with homebrew

New version can be found by reading the output of brew install readline

My output: readline 8.0.0 is already installed and up-to-date

Old version can be found by load error

My error (Note the 7): Library not loaded: /usr/local/opt/readline/lib/libreadline.7.dylib (LoadError)

ln -s new_version/path/to/readline original_version/path/to/readline

In my case my command was

ln -s /usr/local/opt/readline/lib/libreadline.8.0.dylib /usr/local/opt/readline/lib/libreadline.7.dylib

My symptoms started showing up after a `brew cleanup`. This solved it! – Kieran E Feb 06 '19 at 00:11
Thank you so much for explaining how to think this through. That worked perfectly for me. – Avram Sep 04 '19 at 09:49

I fixed this issue by simply adding this gem gem 'rb-readline' and running bundle.

rb-readline

This is a standard fix to this issue try this.. It should get you going

brew rm -f readline

brew install readline

brew link readline --force

here is a reference link rails console doesn't load due to libreadline

Another issue might be which version of ruby is in your path - double check that as well.

ruby -v
ls -la `which ruby`

then check your PATH
