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 si

Answer 1

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

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

Answer 3

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

Answer 4

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

Answer 5

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

rb-readline
