Solved ruby-on-rails command-line ruby-on-rails-5 rails-console

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.

Running via Spring preloader in process 6457

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 – Frantz 5/11, 2016 at 7:29

Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib is the issue – Frantz 5/11, 2016 at 7:30

How do i fix this? – Permatron 5/11, 2016 at 7:32

i need to know what you have updated – Frantz 5/11, 2016 at 7:33

Please check my answer(accepted) here #37739434 – Attribute 5/11, 2016 at 7:58

Read my answer. Try it before you start messing with soft-links and other suggested answers. – Academe 24/8, 2017 at 2:49

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

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 – Hildie 23/1, 2018 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 – Shoplifter 15/1, 2019 at 22:1

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 – Eclat 12/2, 2019 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? – Alkalosis 6/3, 2019 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

Worked for me after a strange bug with my Macbook, thanks – Schaper 25/1, 2019 at 13:17

My symptoms started showing up after a brew cleanup. This solved it! – Cucullate 6/2, 2019 at 0:11

Thank you so much for explaining how to think this through. That worked perfectly for me. – Pubis 4/9, 2019 at 9:49

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

rb-readline

Academe answered 26/7, 2017 at 18:8 Comment(0)

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

Frantz answered 5/11, 2016 at 7:35 Comment(0)

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
